Abstract

The invention relates to a switchable bidirectional phase shift network exhibiting a desired differential insertion phase suitable for use as a phase bit in a multi-bit phase shifter. The design is economical in its use of components-six field effect transistors, three inductors and no capacitors, and provides in one switching state a band pass network of low insertion phase and in the other switching state a low pass network of high insertion phase. The rate of change of insertion phase over a range of operating frequencies is substantially equal for the two states.
