集成晶体滤波器—单片、串联单片及混合单片(多片)石英晶体滤波器广泛应用在高频、甚高频、超高频和卫星通信设备,商用和军用、电话FOM设备,以及包括频率综合器和机载导航设备在内的许多其它方面。频率范围从5到180MHz偶而到250MHz,最大无感带宽在30-35MHz以下通常为中心频率的0.25％到0.35％,在必须使用泛音的较高频率时带宽则比较小。近十年来,压电谐振器理论已能对单片滤波器的线性和非线性精确地用模型来描述。虽然大多数晶体滤波器都是全极点网络,但有实频和复频传输零的滤波器设计方法发现用得越来越多。本文介绍一些现代生产的滤波器的例子。
Integrated Crystal Filters - Monolithic, Series Monolithic and Hybrid Monolithic (Multi-Crystal) Quartz Crystal Filters are Widely Used in High Frequency, Vhf, UHF and Satellite Communication Equipment, Commercial and Military FOM Devices for Phones, and Many other aspects include frequency synthesizers and airborne navigation devices. Frequency range from 5 to 180MHz Even to 250MHz, the maximum bandwidth of less than 30-35MHz usually below the center frequency of 0.25% to 0.35%, in overtones have to use the higher frequency bandwidth is relatively small. For nearly a decade, the piezoelectric resonator theory has been able to model the monolithic filter linearly and nonlinearly accurately using models. Although most of the crystal filters are all-pole networks, there are more and more filters used in the design of filters for the transmission of zero and complex frequencies. This article describes some examples of modern production filters.
