Abstract
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.<>
