Abstract
A self-oscillation mixer circuit includes a cascade amplifier circuitry which is composed of a first transistor of a common emitter connection having a collector connected to an emitter of a second transistor of a common base connection, a filter circuitry for deriving an intermediate frequency signal and a resonance circuit adapted to resonate at a local oscillation frequency being connected to the collector of the second transistor and a feedback circuitry connected between the resonance circuitry and the emitter of the first transistor.
