ABSTRACT:
A phase switching circuit adapted for high frequency applications which is operative for shifting the phase of an input signal either by 0.degree. or 180.degree. in response to a control signal. The switching circuit includes two FETs which are coupled together so as to operate in combination to produce the desired phase switching action. The first FET comprises a grounded gate amplifier while the second FET may be configured either as an inverting amplifier or a source follower by changing the polarity of the power supply voltage applied to its output terminal. The two FETs operate in a complimentary fashion so as to provide relatively constant amounts of phase shift and gain.
