Beyond the Datasheet: Engineering PIN Diode RF Switch Performance


PMI would like to thank everyone that attended our first webinar. In this webinar, we explored how PIN diode RF switch performance is shaped by critical design considerations beyond the datasheet. We discussed switching speed, isolation, insertion loss, power handling, and reliability to help engineers evaluate and optimize RF switch solutions.

In case you missed the live event, we invite you to watch the webinar on-demand, or contact us directly at PMI to learn more.

Polaris Semiconductor, PMI, and Ohio State Publish Microwave Journal Feature on Switching-Free Power for RF Circuits


Polaris Semiconductor, Planar Monolithics (PMI) and The Ohio State University have published a technical feature article in the September 2026 issue of Microwave Journal. The article, “Efficient, Switching-Free Buck and Boost Conversion for RF Circuits,” introduces the Polaris Enhanced Linear Regulator (ELR) to the RF design community and documents its design-in to a PMI voltage-variable attenuator, where it eliminated regulator-induced artifacts and improved the attenuator’s dynamic range by more than 30 dB.

High-Performance Power Amplifiers for Aerospace & Defense Applications!


PMI Solid State Power Amplifiers (SSPA) are ruggedized for use in pulsed airborne, naval, and ground radar applications, as well as found in weather forecasting Doppler radar systems and utilized in air traffic control and precision approach radar systems. These power amplifiers offer remarkably high gain up to 53 dB and saturated output power above 40 dBm (10 W) in bandwidths up to 40 GHz.  Form, Fit, Function designs, ROHS & COTS availability.
