ABSTRACT:
A self-oscillating mixer circuit suitable for a television receiver is provided using characteristically a single or two switching diodes. During VHF receiving, the mixer circuit operates in a self-oscillating mixing mode under an optimum bias condition, while, during UHF receiving, it operates under an optimum bias condition for intermediate frequency amplification, ceasing its local oscillation.
