Abstract
An apparatus for providing electronically tunable biphase modulation including an input and a first switch having a first output, a second output and a first input coupled to the input. The first switch couples the first input to either the first output or to the second output in response to a modulating signal. The apparatus also includes a first signal path having a first phase shift and a second signal path having a second phase shift different than the first phase shift. The first signal path is coupled to the first output and the second signal path is coupled to the second output. The apparatus also includes a second switch having a first input coupled to the first signal path, a second input coupled to the second signal path and a terminal output.
