Description

Technical field [0001] The invention relates to a duplex tower top amplifier used in a mobile communication system, in particular to a highly integrated general duplexer module used for a duplex tower top amplifier. Background technique [0002] In the current mobile communication system, tower top power amplifier (tower amplifier) ​​technology is widely used, including simplex tower amplifier and duplex tower amplifier. The principle of its duplex tower amplifier is: its downlink signal increases its output power through PA to expand coverage; its uplink signal is amplified with low noise through LNA to improve receiving sensitivity; duplex tower amplifier must also have Two-way bypass function to ensure uninterrupted two-way communication signals. In the traditional duplex tower, the functional components are separated, that is, they are connected through connectors (such as SMA) and cables, so there are complex structures, large losses, high standing wave ratios, and unf...
