The Absolute Calibration of Periodic Microwave Phase Shifters without a Standard Phase Shifter
IEEE Transactions on Microwave Theory and Techniques, 1972An absolute calibration procedure for periodic microwave phase shifters is described. Increments on the phase shifter are compared by substitution with a reproducible phase-shift step of initially unknown value. The periodic nature of the phase shifter provides a reference phase shift of 360/spl deg/, and alternative methods are outlined for the ...

A Nanomechanical Phase Shifter
Science, 2014Applied Physics![Figure][1] CREDIT: COURTESY OF M. POOT Information can be encoded in optical signals with a variety of parameters, usually wavelength, polarization, or phase. However, as signals propagate down optic fibers or around optical circuits, they can disperse; that is, they ...

Wide-band monolithic phase shifter
IEEE Transactions on Electron Devices, 1984A wide-band monolithic phase shifter operating in the 2-8- GHz frequency range is described. Six GaAs FET's per bit are used as switch elements in a bridge configuration which alternatively becomes a high-pass or a low-pass section. Their low-impedance state is modeled as a resistor, the high-impedance state as a combination of capacitors and resistors.

1967 G-MTT International Microwave Symposium Digest, 1967
A diagram of the microstrip ferroelectric phase shifter is shown in Fig. 1(a). The nominal thickness of the ferroelectric material is 10 mils. As the dielectric constant of the ferroelectric is very high, the impedance af the microstrip line (~15 mils wide) is comparatively low. For matching purposes quarter-wave transformers of Ti0/sub 2/ were used. A

On the generalised loaded-line phase shifter
Proceedings of 1995 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference, 2002The loaded-line configuration for digital phase shifters is considered for the general situation of different switching admittances. Simple closed-form expressions are derived for the usual case of admittances separated by a quarter-wavelength transmission line.

RF Phase Shifters for Phased Arrays
2011Phase shifters are essential components in a phased array for adjusting the phase of each antenna path and steering the beam. There are various types of conventional RF phase shifters, and they are analyzed in detail in this chapter.

This chapter presents design, analysis and applications of various microwave phase shifters based on varactor diodes, p-i-n diodes and switched delay lines. Design and analysis of continuous variable and constant insertion loss of four-quadrant microwave phase shifters based on p-i-n diodes are described.

Quantities of phase shifters in phased arrays
2008 IEEE Antennas and Propagation Society International Symposium, 2008The one-element/one-phase shifter phased array does not represent the generalized phased array configuration. The generalized phased array consists of radiating elements, a subarray forming network (SFN), and variable phase shifters. The SFN is, in theory, a lossless network containing neither ohmic nor coupling losses.

Publisher Summary This chapter describes the phase shifter. In a measurement circuit, a microwave source supplies two signal paths through a power splitter. Power passes in one of the signal paths through a test section to the left side arm of a magic tee. It passes directly to the right side arm of the magic tee in the other path.

A unified method for phase shifter computation
ACM Transactions on Design Automation of Electronic Systems, 2005Phase shifters are used to shift the bit sequences produced by the successive stages of a built-in test pattern generator (TPG) based on a linear finite state machine (LFSM) by a specified amount ( phase shift ) relative to the characteristic sequence.
