Abstract :
This paper reports the performances of several broadband monolithic SiGe MMICs suitable for phased array radar applications. The amplitude and phase control MMIC designs are based on an optimized SiGe PIN diode offered by IBM 5-HP SiGe foundry process. Utilizing this diode, several control circuitries including a broadband (1-20 GHz) monolithic SPDT switch, a five port transfer switch, a 6-bit phase shifter, and a 5-bit attenuator, all operating over 7-11 GHz are designed. Also, the design and performance of a SiGe HBT variable gain cascode amplifier that combines the functionality of an amplifier and an attenuator into one MMIC is described
