Abstract :
A microwave signal processing (MSP) architecture is presented for active phased array beam forming and steering. A large scale network, comprising 63 power dividers and 32 pairs of orthogonal phase-amplitude controllers, has been successfully developed in a single GaAs MMIC. This megalithic chip could mark an epoch in phased-array antenna systems.
