Abstract

The embodiment of the invention relates to a power amplifier packaging device and base station equipment. The power amplifier packaging device comprises a shell and power amplifier pipes, wherein the power amplifiers are arranged in the shell and placed in parallel corresponding to radio frequency channels, and isolation plates used for absorbing interference electric magnetic waves sent by the power amplifier pipes is arranged between the power amplifier pipes. The base station equipment comprises a plurality of radio frequency channels, a sending antenna and the power amplifier packaging device. According to the power amplifier packaging device and the base station equipment, materials capable of absorbing interference electric magnetic waves sent by the power amplifier pipes are made into the isolation plates of the power amplifier packaging device, an electric magnetic band gap structure and the shell and are used for absorbing the interference electric magnetic waves generated among the power amplifier pipes, thus the power amplifier pipes corresponding to the radio frequency channels are placed in a package, the requirement on isolation among the power amplifier pipes is met, and the invention has the advantages of simple manufacture process, small volume and low cost.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a power amplifier packaging device and base station equipment. Background technique [0002] In the new generation of time division duplex (Time Division Duplex, referred to as TDD) mode wireless communication system, such as time division synchronous code division multiple access (Time Division-Synchronous Code Division Multiple Access, referred to as TD-SCDMA), global microwave access interconnection Interoperability (World Interoperability for Microwave Access, referred to as WiMAX), long-term evolution (Long Term Evoluted, referred to as LTE), due to the extensive use of radio frequency identification and other technologies of smart antennas, it is necessary to increase the number of radio frequency channels to improve the sensitivity of the wireless communication system. Especially in the base station equipment of the wireless communication system, there can be up to ...
