Abstract
Power amplifiers for a next generation of T/R-modules in future active array antennas are realized as monolithically integrated circuits on the bases of novel AlGaN/GaN HEMT structures. Both, driver and high power amplifiers are designed for X-band frequencies. The monolithically integrated circuits (MMICs) are designed, simulated and fabricated using a novel via-hole microstrip technology. Output power levels of 1.6 W (32 dBm) for the driver amplifier (DA) and 20 W (43 dBm) for the high power amplifier (HPA) are measured. An amplifier chain circuitry, with mounted GaN DA and HPA MMICs, is designed based on a multi-layer LTCC technology
未来有源阵列天线中用于新一代T/ r模块的功率放大器是基于新型AlGaN/GaN HEMT结构的单片集成电路实现的。驱动器和高功率放大器都是为x波段频率设计的。采用一种新颖的过孔微带技术设计、模拟和制作了单片集成电路。驱动放大器(DA)的输出功率为1.6 W (32dbm)，高功率放大器(HPA)的输出功率为20 W (43dbm)。基于多层LTCC技术，设计了一种带有GaN、DA和HPA mmic的放大器链电路
