Krytar 3 dB 90 Degree Hybrids. Covers 0.5 - 40 GHz (.pdf)
90 degree hybrids are used in circuits requiring a balanced division of power into two transmission lines with 90 degree separation of phase. Applications include signal splitters, combiners, balanced mixers, imagerejection mixers, phase shifters, diplexers, switches and antenna feed networks

Trends in Microwave/Millimeter-Wave Front-End Technology
on a single chip. Operating in the 3 to 6V drain bias throw switch matrixes as well as compact 5 or 6-bit phase. range, this process combines low noise figure (1dB at 26 shifters. Campbell [2] has reported the development of a K-. GHz), high power density (.8W/mm) and good linearity (>35 band phase shifter

Adjustable MM-Wave Gain Equalizers (.pdf)
Growing demand for high communication bandwidths has led to considerable development of systems operating at millimeter-wave frequencies. These systems, in turn, stimulate research and development efforts of 26 to 40 GHz components such as TWT and solid-state amplifiers and phase shifters

MICRO: Behind the Mask
photomasks include specialized structures that enhance the contrast and resolution of the image that will be transferred to the wafer. Resolution-enhancement techniques add or subtract small features from the pattern to improve the fidelity of the transferred image. Phase shifters manipulate light

Rotman Lens Design and Simulation in Software
Since its invention in the early 1960s [1], the Rotman Lens has proven itself to be a useful beamformer for designers of electronically scanned arrays. Inherent in its design is a true time delay phase shift capability that is independent of frequency and removes the need for costly phase shifters

Phased Arrays
transmitter or receiver either directly or via a feeder, but is coupled to the driven element only by the fields. Other types of parasitic phased arrays are possible such as loop, slot, microstrip, cavity and hybrid arrays. Driven phased arrays utilize a phase shifter, a device for adjusting the phase

TA031: GaAs X-Band Multifunction Control MMIC Using the MSAG(R) Process
This paper describes efforts to achieve first pass design success for an X-band control MMIC consisting of multi-bit phase shifter, multi-bit attenuator, amplifier and serial-to-parallel converter functions using MSAG(R) Process 5. A discussion of the merits of multifunction MMIC integration using
