Problems solved by technology
Although this traditional connection method effectively reduces the shaking at the connection of the output port of the cavity filter, it leads to many connector nodes on the signal transmission path between the power amplifier module and the cavity filter, and the loss of the transmission signal is large; The quality and performance requirements are also very high, and at the same time, a larger operating space is required between the power amplifier module and the cavity filter

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] figure 2 It is a schematic diagram of the connection structure between the present invention and the cavity filter. The flexible radio frequency cable (6) is fixedly connected to the output port of the cavity filter (4) through the central conductor (5); the other end of the flexible radio frequency cable (6) is fixedly connected to the second BMA radio frequency connector (8). The central conductor (5) can be a metal wire exposed after the insulation layer is stripped at one end of the flexible radio frequency cable (6), and is fixedly connected to the output port of the cavity filter (4); it can also be a separate metal conductor, the One end is fixedly connected to one end of the flexible radio frequency cable (6), and the other end is fixedly connected to the output port of the cavity filter (4). BMA RF connector 2 (8) and center conductor...

The invention discloses a blind-mating connection device in a remote radio unit (RRU), aiming to ensure that under the premise that the joint of the cavity filter output port does not shake, the number of connector nodes on the signal transmission path between the cavity filter and a power amplifier module is reduced and the transmission performance of signal can be increased. The technical points of the invention are as follows: a BMA radio-frequency connector A (9) is connected with the input port of the power amplifier module (1) and fastened on the outer wall of the power amplifier module(1); one end of a flexible radio-frequency cable (6) is fixedly connected with a BMA radio-frequency connector B (8), the other end is connected with the output port of the cavity filter (4) through a central conductor (5); the central conductor (5) and the BMA radio-frequency connector B (8) are fastened on the wall of the cavity filter (4); and the BMA radio-frequency connector A (9) is splicedwith the BMA radio-frequency connector B (8). The invention is especially suitable for the outdoor and indoor radio-frequency subsystems of the third-generation mobile communication base station.
Description
technical field [0001] The invention relates to a radio frequency coaxial connection device in electronic plug-ins, in particular to a blind plug connection device between a radio remote equipment RRU power amplification module and a cavity filter. Background technique [0002] In practical applications, shaking at the connection of the output port of the cavity filter in the RRU part of the remote radio equipment will seriously affect the filtering performance of the cavity filter. In the prior art, in order to eliminate the influence of shaking at the connection point on the performance of the cavity filter, a cable assembly is used to realize the connection between the cavity filter and the power amplification module. The cable assembly consists of connectors at both ends and a flexible RF cable in the middle. The traditional connection between the power amplifier module and the cavity filter is as follows: figure 1 As shown: the power amplifier module (1) and the cavit...
