RADIO FREQUENCY FRONT END FOR TELEVISION BAND RECEIVER AND SPECTRUM SENSOR

摘要

A radio frequency front end for a television band receiver and spectrum sensor includes a low noise amplifier that amplifies a received signal output of a radio frequency antenna connected to the radio frequency front end, a pin diode attenuator circuit that selectively attenuates an output of the low noise amplifier, and a buffer amplifier that amplifies an output of the pin diode attenuator.
