A frequency divider is disclosed that includes two bipolar transistors coupled as a Darlington pair, where the base of the first transistor receives an input signal to be divided, and where the common collectors of the transistors generate an output signal having a frequency equal to one-half or other integer submultiple of the input signal. The frequency divider also includes a feedback network operable for coupling a portion of the output signal from the output side of the transistors to the input side of the transistors. Such a frequency divider can provide signal conversion gain at microwave frequencies.
