摘要

采用全单块TM/sub 110/双模介质谐振器，研制了一种800-MHz频段的小尺寸、高功率双工器。在20mhz带宽下，TX滤波器的插入损耗小于0.35 dB;在40mhz带宽下，RX滤波器的插入损耗小于0.47 dB。体积小于3000cm /sup /，约占可重入腔谐振器滤波器的20%。这种双工器对当前和未来的蜂窝基站都很有用。

800 MHz high-power duplexer using TM dual mode dielectric resonators

A small-size, high-power duplexer in the 800-MHz band has been developed by using whole monoblock TM/sub 110/ dual-mode dielectric resonators. Insertion loss is less than 0.35 dB over a 20-MHz bandwidth in a TX filter and less than 0.47 dB over a 40-MHz bandwidth in a RX filter. Volume is less than 3000 cm/sup 3/, which corresponds to about 20% of the reentrant cavity resonator filter. This duplexer is useful for current and future cellular base stations.<>
