Abstract

The invention discloses a novel fixing device and an assembling method for high-power radio frequency power amplifiers. The fixing device comprises a radiating base, a PCB (printed circuit board) board and a U-shaped piece. The PCB board is arranged tightly on the upper surface layer of the radiating base and provided with a center hole and a pair of fixing holes for connecting, a group of welding pads are arranged along the surrounding edge of the center hole; the central part of the U-shaped piece is an arc-shaped groove body, the upper two sides extend outward to form lugs respectively, each lug is provided with a fixing hole and is connected with the PCB board through an adjusting protection retaining part and a screw which penetrates through the fixing hole;a high-power radio frequency power amplifier is pressed on the radiating base by the central arc-shaped groove body of the U-shaped piece through downward pressure; and the U-shaped piece, the PCB board and the radiating base are connected by the screws or bolts which penetrate through the fixing holes on the lugs. By the assembling method, the high-power radio frequency power amplifiers can be assembled with low cost, good grounding and radiating of the radio frequency amplifiers can be guaranteed, performance consistency of the high-power radio frequency power amplifiers is improved, and production and assembly of the high-power radio frequency power amplifiers are facilitated.

Description

technical field [0001] The present invention relates to the field of communication equipment, and more particularly, to an installation device for a radio frequency power amplifier of communication equipment and a method for realizing installation using the same. Background technique [0002] The RF power amplifier is an important part of various wireless transmitters. In the transmission system, the output power of the RF power amplifier can be as large as several 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 special power amplifier module, which guarantees the grounding effect and heat dissipation performance, but the cost is high, and each special RF power amplifier module requires a specific installation structure to cooperate, which brings great adv...
