The utility model aims to provide an improved structure for WCDMA power amplifier with small volume, convenient installation and good radiating effect. The utility model provides the technical scheme that a main power amplifier module, an adjacent channel receiver module and an auxiliary power amplifier are arranged as one body side by side to obtain the technical effect of convenient installation, good heat dissipation and small volume. The utility model is suitable for the application field of power amplifier for mobile communication base station.
Description
Technical field
The utility model relates to a kind of improvement structure of power amplifier, particularly a kind of improvement structure of WCDMA base station down linear power amplifier.
Background technology
In the prior art, the structure of WCDMA linear down power amplifier is divided into two classes mostly, one class is that main power amplifier module and neighboring trace receiver module stack, and delay line partly has independent trough, this structure is unfavorable for the heat radiation of main power amplifier when power amplifier is worked, also be not easy to install, and overall volume is bigger; Another kind of is that main power amplifier is independent of a module, and auxilliary power amplifier is also independent, and two modules are separately installed as a module, and the shortcoming of this power-like amplifier is to be installed separately, and makes troubles to actual installation practice.
Summary of the invention
Technical purpose of the present utility model is to overcome in the prior art, WCDMA base station down linear power amplifier volume is big, radiating effect is poor, inconvenient technological deficiency is installed, provide a kind of volume little, easy for installation, the WCDMA power amplifier of good heat dissipation effect improves structure.
For realizing above technical purpose, the technical solution of the utility model is: a kind of WCDMA linear down power amplifier improves structure, includes shell, main power amplifier module, neighboring trace receiver module, auxilliary power amplifier module; The main power amplifier module of described power amplifier and neighboring trace receiver module, auxilliary power amplifier module horizontal Tile fuse, and main power amplifier module is connected with auxilliary power amplifier module electric wire with the neighboring trace receiver module by connecting plate.
In the utility model, also include monitoring module, described monitoring module is located at neighboring trace receiver module top by double receptacle holders.Be connected by pcb board between main power amplifier module and the monitoring module, in the delay line collection trim and the space between the loam cake in the enclosure, thereby dwindled the volume of power amplifier; Heat pipe is equipped with in the box body bottom, trim is provided with the heat dissipation ventilation hole, and power amplifier is dispelled the heat, and has guaranteed the operate as normal of power amplifier.
Useful technique effect of the present utility model is: main power amplifier module, neighboring trace receiver module, auxilliary power amplifier module become one owing to being arranged side by side, made things convenient for installation, and be beneficial to heat radiation, monitor board is erected at above the neighboring trace receiver module, in the delay line collection trim and the space between the loam cake in the enclosure, owing to do not need independent trough, saved the space of the device of whole power amplifier, make the smaller and more exquisite practicality of volume of power amplifier.
Description of drawings
Fig. 1 is that the utility model power amplifier improves main power amplifier module, neighboring trace receiver module, monitor board module in the structure, the structural representation that auxilliary power amplifier module and row of horizontal fuse;
