Abstract

The invention discloses a low-loss and high-selectivity clutter suppression type base station duplexer, relates to the technical field of communication products, and aims to solve the problem that an internal signal is unstable due to the fact that an existing base station duplexer is easily influenced by external factors during use. A duplexer body is installed below the upper movable gland structure, a lower fixed bearing structure is arranged below the duplexer body, a stable base is installed below the lower fixed bearing structure, a fixed block is arranged on one side of the lower fixed bearing structure, and a control structure is installed above the upper movable gland structure. An annular inner cavity is formed in the duplexer main body, a moisture-proof plate is installed at the bottom of the lower fixed bearing structure, a graphite block is installed on the surface of the moisture-proof plate, the graphite block is fixedly connected with the surface of the moisture-proof plate, a wear-resistant block is arranged on one side of the graphite block, and an anti-interference unit is installed on the surface of the lower fixed bearing structure.

Description

technical field [0001] The invention relates to the technical field of communication products, in particular to a base station duplexer with low loss and high selectivity for clutter suppression. Background technique [0002] The duplexer is a different-frequency duplex radio station and the main accessory of the repeater station. Its function is to isolate the transmitting and receiving signals to ensure that both receiving and transmitting can work normally at the same time. It is composed of two sets of stop-band filters with different frequencies Composition, to avoid the transmission of the local transmission signal to the receiver, the general duplexer is composed of six stop-band filters (notch filters), each resonant at the transmission and reception frequency. The filter at the receiving end resonates at the transmitting frequency, and prevents the transmission power from entering the receiver in series, and the filter at the transmitting end resonates at the receiv...
