Monolithic High Power 300 Watt, S-Band, HMIC PIN Diode Limiter

A monolithic multi-stage high power silicon/HMIC PIN diode limiter that covers the full range of UHF to S-Band frequencies has been designed that is capable of handling up to 300 watts CW of incident RF power. This monolithic MMIC limiter approach has been enabled by recent improvements to MACOM's state-of-the-art HMIC PIN diode technology. This MMIC design will be able to produce superior RF performance and power handling when compared to present hybrid assembled limiters that are based upon chip and wire integration of discrete PIN diodes but having a dramatic reduction the overall footprint and a significant reduction in device cost.
