Abstract :
This paper describes the design of a space diversity microwave combiner which is used in a direct demodulation microwave link (16 QAM 140 Mbits/s) in the 6.4-7.1 GHz band. The space diversity microwave combiner consists of two variable gain low noise amplifiers (in MMIC technology), a tunable attenuator and a balancing delay line, a controllable endless phase shifter and a summing network.
