A bi-phase modulator is a component of many complex IQ and quadrature modulator systems, and performs the task of two-state phase modulation (between 0 and 180 degrees) and is often paired with a continuously variable attenuator to provide both amplitude and phase modulation.. Bi-phase modulators can be used directly to produce binary phase shift keying ..

A Radio Frequency mixer is a three-port passive or active device that combines two or more signals into one or two composite output signals, and is the backbone of heterodyne and superheterodyne communications technologies. The purpose of a mixer is to produce a signal at a new frequency, while preserving other characteristics of the initial ..
