Abstract
A wideband and controllable-gain amplifier utilising a new parallel feedback technique, which can enhance the bandwidth and can control the gain keeping output DC voltages constant, has been developed using AlGaAs/GaAs HBT technology in monolithic form. This IC achieves a wide bandwidth of DC-9 GHz, and a controllable gain range of 8–20 dB with a total power dissipation of 640 mW at a power supply voltage of 9 V.Keywords
