Abstract
A self-oscillating mixer is disclosed, and includes two bipolar transistors coupled as a Darlington pair, where the base of the first transistor receives an input signal, and where the common collectors of the transistors generate an output signal; and a feedback resonator operable for coupling signals at the local-oscillator frequency from the output side of the transistors to the input side of the transistors. Such a self-oscillating mixer can provide signal conversion gain at microwave frequencies.
