ABSTRACT:
A digital phase shift apparatus having a pair of single gate FETs which are connected in a common source configuration. Transmission line segments which respectively connect the sources and drains of the FET pair, provides a phase shift to an applied RF signal. The operating FET provides signal gain as well as switch the signal path length.
