Ku-band modular MMICs for up to 5W power blocks for VSAT applications

An innovative approach to a quick design of multi-watts Ku-band power amplifiers for VSAT up-link applications is proposed. Starting from a set of specifically developed MMIC power macrocells, a modular imptementation is used to combine them into power modules requiring no adjustment and delivering up to 5W with 24dB associated gain in the 14-15.5GHz frequency band. The basic MMIC single chips exhibit a ldB gain compression output power of respectively : 200mW, 500mW and 1.6W. 3 W and 5W power modules are presented as examples
