Abstract
A novel GaAs MMIC active filter structure based on the lumped and transversal technique is proposed for operation in the X-band. This new structure includes a tuned amplifier in order to improve the band edge rejection. A design example of a bandpass filter centered @ 7.5 GHz with 2 dB passband ripple and 30 dB rejection @1 GHz apart from passband edges is presented in terms of computer simulated results and layout. The simulated results demonstrate its superior performance when compared with the traditional lumped and transversal technique.

An Angular Displacement Sensor Based on Microwave Transversal Signal Interference Principle

TL;DR: In this article, a rotational angle microwave sensor with a high dynamic range and sensitivity for detecting angular displacement is presented, which exploits the spectral separation between two notch frequencies or transmission zeros that are generated in its transfer function, and whose value varies as a function of the rotation angle.

An octave-band MMIC active filter

Abstract: The design, fabrication, and measurement of a GaAs monolithic, active bandpass filter with a passband from 4 to 8 GHz is described. The circuit uses a set of cascaded lumped- and distributed-element LC circuits isolated by a feedback amplifier to realize an equivalent fourth-order filter response. The final circuit was fabricated on a 3-mm*2-mm GaAs substrate. >
