Radio communication equipment

Abstract

A radio frequency communication device comprises machine case, power amplifier module, filter, adapter one end of which is directly connected with power amplifier module, the other end of which is connected with filter. The power amplifier module and filter is installed in machine case, and the bottom plate of power amplifier module and filter is integrated with the machine case. The power amplifier module is directly connected with filter by adapter, which effectively avoids signal spoilage resulting from radio frequency cable adopted by existing technology and coil direction of radio frequency cable in machine case which makes device more compact and beautiful. The integral design effectively reduces cost, size and weight of radio frequency communication device.

Problems solved by technology

[0002] like figure 1 As shown, it is a structural schematic diagram of a radio frequency communication device in the prior art, which includes a chassis, and a power amplifier module and a filter installed in the chassis, wherein the power amplifier module and the filter are connected through a radio frequency cable. In the existing design 1. During the installation process, the power amplifier module and filter are usually set separately. When assembling, put the power amplifier module and filter into the chassis and then connect them through radio frequency cables. According to this radio frequency communication device in the prior art , because the power amplifier module and the filter are connected by radio frequency cables, and the impedance of the radio frequency cables themselves will inevitably cause losses to the transmission of radio frequency signals, resulting in unnecessary signal loss, and this The loss is usually 0.2dB or more, which increases the performance requirements of the power amplifier and increases the difficulty of debugging the power amplifier. In addition, because the power amplifier module and the filter are connected by radio frequency cables, and the radio frequency cables are in the chassis The coiled direction will make the overall layout messy, reducing the compactness and aesthetics of the overall layout of the device
