Problems solved by technology
[0003] However, the existing power amplifiers are often installed inside the transmitter by welding, and the power supply, RF input, and RF output interfaces of the power amplifier need to be connected to the transmitter through cables.
When the power amplifier is damaged and needs to be repaired, it is necessary to use tools such as a soldering iron to disassemble the power amplifier. In addition, many screw components and connecting cables need to be removed, resulting in low maintenance efficiency of the power amplifier, high transmitter outage rate and maintenance high cost

The embodiment of the invention discloses a blind-mating power amplifier and a transmitter. The power amplifier comprises a casing;, a printed circuit board and a heat dissipation device. The printedcircuit board and the heat dissipation device are both arranged in the casing. A power amplifier tube is arranged on one side of the printed circuit board, and the heat dissipation device is located on the side, deviating from the power amplifier tube, of the printed circuit board. A high-low frequency hybrid plug and a high-frequency high-power quick collision plug are arranged on the first sideface of the casing. The high-low frequency hybrid plug comprises a power supply interface and a radio frequency input interface. The high-frequency high-power quick collision plug is a radio frequencyoutput interface. The power supply interface is electrically connected with the power end of the power amplifier tube. The radio frequency input interface is electrically connected with the input end of the power amplifier tube. The radio frequency output interface is electrically connected with the output end of the power amplifier tube. The power amplifier can be installed in a transmitter inan inserted mode. The maintenance efficiency of the power amplifier is greatly improved, and the stop rate of the transmitter is reduced.
Description
technical field [0001] The embodiments of the present invention relate to the field of transmitters, in particular to a blind-insertion power amplifier and a transmitter. Background technique [0002] The transmitter is mainly used to complete the modulation of the low-frequency signal to the high-frequency carrier. It is a device that transmits the signal at a certain frequency. It is widely used in various civilian and military equipment such as television, radio, and radar. It can be mainly divided into frequency modulation Transmitters and AM transmitters and other types. Among them, the power amplifier is the core component of the transmitter, as well as its core heating unit, and it is also a vulnerable device. In order to reduce the off-air rate of the transmitter, it is necessary to improve the maintenance efficiency of the power amplifier. [0003] However, the existing power amplifiers are often installed inside the transmitter by welding, and the power supply, ra...
