Abstract

A tunable reflection‐type phase shifter, which consists of a quadrature coupler and a piezoelectric transducer (PET), is presented. The proposed phase shifter shows double phase shifts of the conventional PET‐controlled phase shifter by calculation. Measured results of the phase shifter show a maximum phase shift of 132° with respect to the unperturbed condition at 9.7 GHz. An insertion loss (S~21~) and a return loss (S~11~) are better than 1.85 and 14.2 dB, respectively, and the insertion‐loss variation is within ±0.46 dB at 9.7 GHz. © 2011 Wiley Periodicals, Inc.

## Abstract We report a miniaturized phase shifter operating in the frequency range from 5 to 7 GHz for noise‐parameter extraction. Such a tunable solid‐state unit represents a significant reduction in the size and mass as a source‐pull component, compared to its mechanical counterparts. It provide
