low insertion loss, high stop band attenuation, steepened filter curve through additional stop poles

LP-C55/G51A Combiner:

Commonly-used different frequency combiner is formed by two connecting pass-band filters. The performance index of different frequency combiner not only describes performance requirements for the two filters respectively, such as frequency range, insertion loss, return loss and out-off-band inhibition, but also the availability on the mutual influence between the two filters performance requirements, such as isolation or dispatch inhibition, which refers to the stop-band attenuation of two pass band filters, except in some specific occasions, the attenuation from receiver port to transmitter port in the operation frequency range of transmitter port, and the attenuation from transmitter port to receiver port in the operation frequency range of receiver port.

Application: The combiners combine the multi-channel signals into one-way signals, and are applied to GSM, CDMA dual-frequency direct amplifier station and indoor coverage systems, with characteristics of small volume and wide isolation between the channels.

Design and construction: The Band-pass Filter consists of 6 high Q resonators.
