Abstract :
A novel design approach to a wideband GaAs microwave monolithic amplifier is presented using the principle of feedback and active matching networks. The multistage amplifier utilises a unique biasing circuit which requires only one biasing voltage. A 6-18 GHz multistage amplifier has been demonstrated using the proposed approach. The amplifier has low input/output VSWR, a maximum of 20 dB gain and at least 15 dBm of output power.
