High Voltage Breakdown (HVB) HPA MMIC based on GaAs pHEMTs technology represents a useful way for high power RF application. To increase the breakdown voltage respect to conventional device, a field-plate (FP) gate structure is implemented in our standard 0.5 μm process. With this solution the off-state breakdown voltage of the device has been improved from 18V to 28V, while keeping constant the drain...
This paper presents two MMIC broadband high power amplifiers of 4 mm of periphery at the output stage in the frequency band 2-6 GHz. The amplifiers are based on Al-GaN/GaN high electron mobility transistor (HEMT) technology on SiC substrate. They have been fabricated in two different european foundries: SELEX Sistemi Integrati and QINETIQ. SELEX has a gate process technology of 0.5 mum, and devices...
In this article the design, fabrication and test of X-band and 2-18 GHz wideband high power SPDT MMIC switches in GaN technology are presented. Said switches have demonstrated state-of-the-art performance and RF fabrication yields better than 65%. In particular the X-band switch exhibits an on-state power handling capability of better than 37 dBm at the 1 dB insertion loss compression point and the...
