Abstract

Radio receiver with voltage tuning for use with a low voltage supply, comprising the combination of a radio frequency input stage in the form of a low pass filter intended to attenuate signals at frequencies higher than that of the desired band, a first local oscillator with voltage tuning to oscillate at a variable frequency in a band higher than the required radio frequency band.
