Digital phase shifter is a type of control device that changes the phase of RF, microwave or millimeter wave signals with practically negligible attenuation. These devices are programmable or can be controlled via a computer interface. Digital phase shifters have a variety of applications, including RF power amplifier linearization/RF distortion, amplitude and phase modulation, variable attenuators, and fiber optics. Different types of digital phase shifters such as 4-bit, 5-bit, 6-bit, and 8-bit digital phase shifters, etc. are used for telecommunication, VSAT communications, navigation, and radar. A digital phase shifter consists of high performance GaAs switches, low/high pass filter, and integral TTL driver. GaAs switches have little power consumption, fast switching time, and extremely low switching transients. Depending on their end-use, different kinds of digital phase shifters are used for different applications. For example, 8-bit digital phase shifters are designed to be used in a broad range of applications including beam forming networks, active antenna systems, distributed antenna systems, and phased array applications.

One of the key challenges faced by the digital phase shifter is that it is difficult to maintain linearity which provides near constant phase shift over an octave in these devices. Usage of technologies such as UltraCMOS technology, an advanced form of SOI, is the key trend observed in the global digital phase shifter market. This technology has proved to be quite effective at solving digital phase shifter market's biggest challenge, which is linearity. Digital phase shifters, with phase range of 90, are used in wireless communication for single side band generation, image rejection, and IQ modulation. Hence, 90° digital phase shifters are in high demand.
