It is shown that surface transverse wave (STW) resonant devices are not only very well suited for stable oscillator applications but have some unique features offering greater design flexibility than their surface acoustic wave (SAW) counterparts. Various designs for single- and multimode resonators and resonator filters are presented, and their properties in respect to applications in stable fundamental-mode fixed-frequency and voltage-controlled oscillators in the range of 750 MHz to 2 GHz are discussed. Characteristics of SAW and STW two-port metal strip resonators using identical designs are compared. Data from frequency trimming on STW resonators, using heavy ion bombardment, are presented.
结果表明，表面横波（STW）谐振器件不仅非常适合稳定振荡器应用，而且具有一些独特的特性，比其表面声波（SAW）同类器件提供了更大的设计灵活性。本文介绍了单模和多模谐振器以及谐振器滤波器的各种设计，并讨论了它们在750 MHz至2 GHz范围内稳定基模固定频率和压控振荡器应用中的特性。比较了采用相同设计的SAW和STW两端口金属条谐振器的特性。给出了使用重离子轰击对STW谐振器进行频率微调的数据。
