摘要

介绍了１５５．５２ＭＨｚ、６２２．０８ＭＨｚ声表面波（ＳＡＷ）、１２４４．１６ＭＨｚ浅体波（ＳＴＷ）压控振荡器（ＶＣＯ）的原理、设计和性能。采用低插损、高Ｑ值的ＳＡＷ延迟线和ＳＴＷ谐振器，高性能微波放大器，变容二极管电移相器，使振荡器具有非常低的相位噪声（＜－１４０ｄＢｃ／Ｈｚａｔ１００ｋＨｚ）、高输出功率（＞９ｄＢｍ）、低温度－频率漂移（＜±３５ｐｐｍ，温度范围：－５～６０℃）、大频率调谐范围（＞４００ｐｐｍ）。

Abstract

This paper discribes the principle

design and performance of the voltage controlled oscillators at 155.52 MHz

622.08 MHz and 1 244.16 MHz using surface acoustic wave（SAW） and surface transverse wave（STW） devices. By using low loss

high Q SAW delay lines or STW resonators and highly efficient tuned amplifier circuits

oscillators have very low noise （ better than -140 dBc/Hz at 100 kHz offset from carrier ）

provide a high output power （ >9 dBm ）

low temperature frequency variations and a tuning range of more than 400 ppm.
