Abstract :
Two solutions to the cross-modulation problem in VHF solid-state TV tuners are described. The first consists of a PIN diode attenuator preceding a common-gate FET amplifier. The second is a cascode arrangement of FET´s designed to provide minimum cross-modulation. The performance of both solutions with respect to gain, noise figure, AGC range and skewing, and cross-modulation is compared to the performance of a 6HA5 amplifier at 200 MHz.
