Abstract

The invention provides an installation device and method of a radio frequency power amplifier with radiating and grounding performances. The installation device comprises a radiating base, a PCB (printed circuit board) and a U-shaped fixed seat, wherein the PCB is tightly covered on the upper surface of the radiating base, a center hole is formed on the PCB, the radio frequency power amplifier is placed in the center hole, the shape of the enter hole is matched with the packaging configuration of the radio frequency power amplifier, and a pair of input and output pin welding discs and a pair of grounding welding discs are distributed along the surrounding edge of the center hole; the U-shaped fixed seat comprises a middle U-shaped seat body, end ears are arranged on the two upper sides of the U-shaped seat body, an internal groove of the U-shaped seat body provides a fixing position for the power amplifier, and the end ears on the two sides of the seat body are provided with fixing holes; and the U-shaped fixed seat, the PCB and the radiating base are connected with one another by virtue of screws or bolts. The installation device can be utilized to provide the installation method with low cost of the power amplifier, can ensure the good grounding and radiating performances of the power amplifier, can improve the performance consistence of the power amplifier, and is convenient to be produced and assembled.

Description

technical field [0001] The invention relates to the field of communication equipment, and more specifically, to a communication equipment radio frequency power amplifier installation device and a method for implementing the installation by using the same. Background technique [0002] The RF power amplifier is an important part of various wireless transmitters. In the transmitting system, the output power of the RF power amplifier can be as large as hundreds of watts. Therefore, the grounding impedance and heat dissipation effect of the RF power amplifier determine the reliability and cost of the entire amplifier, and its installation and fixing methods are extremely critical. [0003] The RF power amplifier uses a dedicated power amplifier module, which guarantees the grounding effect and heat dissipation performance, but the cost is relatively high, and each dedicated power amplifier module requires a specific installation structure to match, which brings more problems to ...
