ABSTRACT:
Positive phase changes with increasing signal level in a high frequency Schottky-gate FET amplifier stage are compensated for by coupling, via an impedance matching circuit, at least one bipolar transistor amplifier stage in cascade with the FET stage. The resultant amplifier is particularly useful in a microwave radio transmitter for a digital radio transmission system.
