8th European Microwave Conference, 1978, 1978
Acoustic waves have several attractive features for device applications. Low velocities lead to compact devices. Use of crystalline materials gives low propagation losses and good reproducibility and stability. Surface acoustic waves offer in addition exceptional versatility, owing to accessibility of the propagation path.

Microwave magnetoelectric devices
2004 14th International Crimean Conference "Microwave and Telecommunication Technology" (IEEE Cat. No.04EX843), 2004One of prospective directions of solid-state electronic engineering is to produce new devices on the basis of magnetoelectric materials. The design and application of a new microstrip microwave filter and attenuator based on composite ferrite-piezoelectric resonators are considered.

Microwave semiconductors devices
Reports on Progress in Physics, 1985The field of microwave semiconductor devices has expanded greatly in recent years, both in the functions that may be performed and the range of devices available for any function. The upper frequency limits of transistor operation have also marched steadily upwards, with millimeter-wave (above 30 GHz) operation being achieved in many laboratories ...
