Brooklyn, NY, June 13, 2025 – Mini-Circuits is proud to have members of its engineering team contributing to the 2025 MicroApps talks at the 2025 IEEE MTT-S International Microwave Symposium (IMS) in San Francisco. Subject matter experts from the company’s MMIC, µCeramIQ™ and RF filter development groups will present on recent innovations in their respective product lines and related applications.

Visitors to IMS 2025 can see Mini-Circuits’ presentations at the times listed below at the IMS MicroApps Theater in the exhibition hall.

Tuesday, June 17th, 2:30 – 2:45 p.m. PT
A 9W Low-Cost GaAs MMIC Power Amplifier
for C & X Band Communications
Carlo Poledrelli

The design and measurement results of a 9W MMIC power amplifier, covering the 7.1 to 8.5 GHz frequency range, is described. The PA was fabricated on a mature 0.25µm GaAs optically-defined gate process with Enhanced Moisture Ruggedness layer. The PA is assembled in a low-cost 6x6mm QFN package and features integrated ESD protection. In CW mode, the amplifier exhibits 28 dB of linear gain and 39.5 dBm of saturated output power, with 34% associated efficiency. Optimal thermal design allows for operation up to 105°C. State-of-the-art performance, enhanced reliability, in conjunction with low-cost technologies, make this PA a very attractive option for C/X band communication systems.

Wednesday, June 18th, 10:30-10:45 a.m. PT
A Dual-Band Channel Sounder Module
for FR1 & FR3 Band Modelling
Daniel Ford

The FR3 bands (7 to 24 GHz) have attracted growing interest as a possible “Goldilocks zone” for next-gen communications networks, balancing the data capacity of millimeter-wave transmissions with the range and low power requirements of sub-6 GHz signals. This talk will present a channel sounder module specially designed and built in collaboration with a research team from NYU WIRELESS to develop the first comprehensive penetration loss model for the 16.95 GHz FR3 band. The system requirements and block diagram will be described and a real-time demonstration performed using the same hardware in the original module.

Thursday, June 18th , 1:15 – 1:30 p.m.
A Tuning Technique for Enhancing Far-Band Rejection
Performance in Suspended Substrate Low Pass Filters
Steve Scheinkopf

Low pass filters are crucial for eliminating unwanted high-frequency signals in communication systems. Achieving enhanced far-band rejection while maintaining a compact design, however, remains a significant challenge. This presentation explores a practical tuning technique to enhance the far-band rejection capabilities of suspended substrate low pass filters. Despite the wideband nature of suspended substrate technology in general, achieving far-band rejection performance can be challenging due to the limitations inherent to transmission lines for wider frequency ranges. The tuning technique discussed aims to address these limitations, ultimately giving designers a practical option to extend far-band rejection performance in low pass filters.
