Abstract of the Disclosure A UHF tuning system for providing linear high gain operation over the entire UHF band comprises a field effect transistor (FET) amplifier coupling a received RF signal to a mixer for developing an IF signal, the IF signal being coupled to an IF processing stage by a signal regulating diode. An AGC control signal is derived from the IF stage for controlling the gain of the FET amplifier which, in turn, is utilized to control the conduction of the regulating diode so as to provide a substantially constant level IF signal to the IF processing stage. The novel arrangement of the present invention permits the field effect transistor to operate at a lower voltage for more efficient thermal operation and increased reliability while providing a high, flat gain characteristic over the entire UHF band.
