FIELD: physics, radio.
SUBSTANCE: invention pertains to reception of radio signals. The phase-compensation preselector-mixer for a radio signal receiver has a radio frequency amplifier, four mixers, two heterodynes, two 90° phase changers, a phase inverter, an adder and a multiple-tuned transformer.
EFFECT: increased reception quality owing to increase in degree of suppression of the reception image channel to the required value σi = 80 dB.
