Barciela<br /> Vigo University, Spain </small> </tr> <br /> <tr> <br /> <i> I have been using Modelithics CLR models for close to 20 years now in my development of High-Power Doherty Amplifiers. I have found that without these models my design cycle time is negatively impacted due to extra design spins required from empirical tuning. Utilizing Modelithics models greatly aids in reducing my design cycle time and limits the amount of board spins required.</i><br /> <small id="Testimonial">Gary Burgin<br /> Sumitomo Electric Device Innovations USA </small> </tr> <br /> <tr> <br /> <i> IMS is excited to continue this partnership. Applying bench-test data to scalable models found in their library (<a href="https://www.modelithics.com/model"> Modelithics COMPLETE Library™ </a>) not only provide valuable performance validation, but also benefits our customer design speed and capabilities. High tech customers design with high tech tools that are supported by Modelithics’ software. Modelithics helps our customers gain access to IMS products and data we know can help solve problems in circuit design easily and with accuracy in pre-prototype development.</i><br /> <small id="Testimonial">J.J. Silvia III<br /> International Manufacturing Services, Inc. </small> </tr> <br /> <tr> <br /> <i> I have been using Modelithics simulation models for over 10 years now. I have had 100% first pass success record in my designs when I use Modelithics CLR, NLD, NLT models, from simple filters, to LNAs, VCOs and nonlinear GaN HPAs. Their team have done some custom Low noise BJT modeling for us, to use in Low phase noise VCOs. After using their models, measured results were very close to simulations. Designing low noise VCOs is a challenging and time-consuming task but using Modelithics custom models helped me gain good confidence and ensured first pass success. I love their prompt customer service. Keep up the good work!</i><br /> <small id="Testimonial">Mohit Shringi<br /> Shure Incorporated </small> </tr> <br /> <tr> <br /> <i> Those models do a great job of matching measured results in a rather difficult circuit. Thanks, Modelithics!</i><br /> <small id="Testimonial">Roger Williams<br /> 3D RF Energy Corp </small> </tr> <br /> <tr> <br /> <i> For years, we resisted purchasing Modelithics models because we had so much experience designing resonant circuits using our internal design compensation rules. Our technicians could “tune up a bad day” and were proud to do so. With the advent of newer communication bands and the availability of precision lumped element components, we could no longer stay ahead of our competitors and deliver to customer expectations. We purchased our first Modelithics license and our engineers immediately began to take advantage of the scalable models. In the years that we’ve been using the library of parts, we’ve seen yield improvements and first pass success on even challenging designs which worked above 18 GHz. Modelithics does an excellent job of keeping their libraries up-to-date with the latest vendor components so that we can take advantage of the advancing art of discrete SMT passive and semiconductor devices. Our technicians don’t miss the challenge as much as we thought that they would. Rather, they now delight in the performance of the precision engineered design running out of the gate.</i><br /> <small id="Testimonial">Walter Gordon, P.E.<br /> Lexatys, LLC </small> </tr> <br /> <tr> <br /> <i> Thank you very much for all of your assistance in setting up the Modelithics libraries. Your service is top notch and you should be very proud of it!</i><br /> <small id="Testimonial">Eric Hoppenjans<br /> Indiana Microelectronics, LLC </small> </tr> <br /> <tr> <br /> <i> I had the task of designing a repeatable capacitive terminated coupled line filters on substrate which is not known for its microwave performance (Isola 370HR), but which is relatively well characterized for its tangent loss and Dk. After having regular discrepancies between model performance and measured data, specifically with the commonly available S-Parameters for the various AVX/ATC capacitors I was using, I decided to utilize the Modelithics AVX model library. This allowed me to make a seamless integration of the capacitor model’s performance into the circuit file but also the model’s ability to change the pad stack or turn them off completely and use the pads within the AWR Design Environment Axiem simulation. That level of flexibility allowed me to generate extremely accurate simulation correlation with my measured data and also acted as a tuning tool for me to predict exactly which capacitor value was going to tune my filter to resonance with excellent frequency precision. This proves to me that published S-Parameters are ok for making rough order of measure design calculations, but when you need to accurately model the design, and have it work and be tuned to the correct frequency on the first iteration, <b>the Modelithics model libraries are the only way to go.</b></i><br /> <small id="Testimonial">Steven Pappas<br /> Rajant Corporation </small> </tr> <br /> <tr> <br /> <i> Thanks you for helping us create great designs - faster and with a higher level of quality! Modelithics models allowed us to better predict performance and correct any deficiencies prior to final component selection and prototype fabrication. Yields were also improved as designs were better centered.</i><br /> <small id="Testimonial">Theo Pantazopoulos<br /> ThinkRF Corporation </small> </tr> <br /> <tr> <br /> <i> We have been using Modelithics models for a gradate course in Microwave Active Circuit Design for two semesters. In this course, students designed, fabricated, and measured active circuits such as gain-matched amplifiers, VCOs, mixers, and low-noise amplifiers. The Modelithics libraries enabled the success of these projects due to their accuracy, ease of use, and breadth of model offerings. We used a wide variety substrate-scalable L,C,R models and diode models for the passives, and BJT/FET non-linear models for the actives. Having all these models available in a single library with the associated layout footprints allowed students to design circuits in a matter of hours, which would simply not be possible otherwise. Of equal importance, the models were quite accurate which resulted in excellent measured/modeled agreement of the circuits that were fabricated. Lastly, the Modelithics team has been extremely supportive, and has helped us by answering many questions along the way. </i><br /> <small id="Testimonial">Matt Heins<br /> University of Texas at Dallas </small> </tr> <br /> <tr> <br /> <i> We are at the point where most MMIC designers won’t do the design unless there is a Modelithics model. [The foundry’s] models work for common circuits. But, for more complex requirements, and when we only got one shot we use your models.</i><br /> <small id="Testimonial">Senior MMIC Designer<br /> US Defense Contractor </small> </tr> <br /> <tr> <br /> <i> Having access to Modelithics library in ADS has proven to be a boon to student productivity as they can now model realistic circuits and can shorten the design-build-test cycle.</i><br /> <small id="Testimonial">Branimir Pejcinovic<br /> Portland State University </small> </tr> <br /> <tr> <br /> <i> The Modelithics Qorvo GaN (Angelov based) models used by SARAS in recent designs have yielded very good results in 2 respects. The models have been accurate enough to produce ‘right first pass’ results with good repeatability. Inclusion of self-heating and temperature scaling also allows degradation over temperature parameters to be observed. Secondly, access to the intrinsic I - V sensing nodes has enabled SARAS to carry out the design work at the device plane rather than the package plane, this has been instrumental in achieving high efficiency back-off mode designs whilst achieving a high degree of linearity performance using a waveform engineering approach. The measurement validation notes that accompany the model give a good idea of the device model envelope and finally whilst the device layout / footprint may seem unimportant it is a very welcome addition when laying out the final design in the simulator!</i><br /> <small id="Testimonial">Jack Brunning<br /> SARAS TECHNOLOGY </small> </tr> <br /> <tr> <br /> <i> My small firm designs MMIC’s for major contractors. In recent years to save costs, contract times decreased 25%. As a result, MMIC designs must achieve production readiness on the first iteration. We shifted from foundry models to Modelithics models and achieved four production-ready first-pass successes in a row. One first pass PA, operating from RF to W band, measured-to-modeled, fit gain within one half dB, power within one half dB and achieved a very competitive PAE over that band. In one LNA, the measured to modeled NF and gain lines were so close, the client thought we forgot to add the measured traces.</i><br /> <small id="Testimonial">David Bever<br /> Aurora Microwave </small> </tr> <br /> <tr> <br /> <i> The model works great. PAE of my part was short of simulated with someone else's model. It was scaled a lot though. I just put the Modelithics model in and it's much closer.</i><br /> <small id="Testimonial">Senior RF Design Engineer <br /> at a major US Defense Electronics firm </small> </tr> <br /> <tr> <br /> <i> Modelithics is the hero of the RF/Microwave engineering profession. I can't think of a single company that has done more to advance our profession from a black art to a science.</i><br /> <small id="Testimonial">Jeff Philips<br /> RF Engineer| Microwave Engineer| Analog Engineer | Electrical Engineer| Hardware Engineer </small> </tr> <br /> <tr> <br /> <i> EM-co-simulation is a critical design step in achieving first pass success. The Modelithics CLR Library for Sonnet Suites significantly simplifies using Modelithics’ lumped element models with physically based Sonnet modeling. Prior to the advent of the Library, designers would manually perform several tasks to extract s-parameters files from Modelithics’ libraries and then import these files into Sonnet. This included keeping track of filenames and certain Global Model parameters. The new CLR Library for Sonnet with Global Models realizes a huge increase in designer accuracy and efficiency by eliminating the need for extraction and associated data file management. Global Model availability within Sonnet enables comprehensive lumped component analysis, such as parameter sweep, substrate variation, optimization, and current visualization.</i><br /> <small id="Testimonial">Rich Carlson <br /> Independent Engineering Services </small> </tr> <br /> <tr> <br /> <i> I’ve been using your custom and CLR models for almost 10 years now, and I find them indispensable for accurate component modeling. The integration with AWR Microwave Office is excellent, and support has always been quick and spot-on. Our whole Microwave Design group appreciates the value Modelithics models bring to our circuit designs.</i><br /> <small id="Testimonial">Senior RF/Microwave Design Engineer<br /> US Defense Contractor </small> </tr> <br /> <tr> <br /> <i> Quickness, professionalism, Best. You and your company give me those images.</i><br /> <small id="Testimonial">Thomas Zhang<br /> Ericsson </small> </tr> <br /> <tr> <br /> <i> I have been using Modelithics CLR libraries for several years, and have come to rely on them for all my simulation work.
