A GaAs monolithic phase detector operating over the frequency range of 1 MHz to 8 GHz, with a phase detection sensitivity factor of up to 1.6 has been developed at TRW. The detector circuit consists of a doubly balanced transconductance multiplier which has a total of 7 FETs and requires only one DC bias point. The detector chip measures 30 x 35 MILS and has a DC power consumption of 100 mW.
