HRD-series duplexer specifications
HRD- series duplexer is an important device which is served for the duplex radio to transceive through one antenna. The Model HRD-150, HRD-230, HRD-350, and HRD-450 of duplexers are comprised of good temperature compensative device and sturdy six cavity resonator. They have the advantages of low insertion loss, high isolation degree, stable performance, and beautiful appearance.
Model-350 of duplexer is specifically designed for the 350MHz cluster communication. It has not only all the performances as the same series of duplexer, but also a very wide working band.
