Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
We claim: 1. A radio frequency front end for a television band receiver and spectrum sensor, comprising: a radio frequency antenna adapted to receive television band signals; a low noise amplifier that amplifies a received signal output of the radio frequency antenna; a pin diode attenuator circuit that selectively attenuates an output of the low noise amplifier; a buffer amplifier that amplifies an output of the pin diode attenuator; a downconverter/tuner that receives an…
