Abstract
Circuitry for shifting a phase of a radio frequency (RF) signal. Mutually dissimilar and electrically coupled portions of an electromagnetic transmission line pattern on one side of a substrate interact with another electromagnetic transmission line pattern on the opposing substrate side to convey a RF signal with a phase shift that is determined by the RF signal frequency and respective dimensions of the electromagnetic transmission line patterns and is substantially constant over a wide bandwidth. With multiple implementations of such opposing electromagnetic transmission line patterns having different pattern dimensions and coupled between RF signal switches, multiple phase shifts can be selectively provided.
