An electronically programmable multimode circuit is described. More particularly,
the present invention is an electronically programmable multimode circuit that
includes a first path and a second path wherein a mode and a signal directional
flow direction is controlled through the selective biasing of the first path and
the second path. A multimode circuit is produced that contains modes such as a
phase shifter mode, an IQ modulation mode, an amplifier mode, a mixer mode, and
a multiplier mode.
