The invention discloses a manufacturing process of a preamplifier module of a Ku-band 40-watt power amplifier, comprising: step 1, cleaning the amplifier preamplifier module cavity, cover plate and circuit board; step 2, cleaning the cover plate and the amplifier preamplifier module The cavity is covered with tin; step 3, sintering the components on the circuit board; step 4, sintering the circuit board and insulators on the cavity of the pre-amplifier module of the amplifier; step 5, debugging and testing the sintered components. This manufacturing process overcomes that the manufacturing process of the preamplifier module of the Ku-band 40-watt power amplifier in the prior art is not scientific and simple enough, and the performance indicators often fail to meet the requirements of the whole machine, and the production efficiency and pass rate are low, and the production cost is high. The problem.
Description
technical field [0001] The invention relates to the field of manufacturing methods of power amplifiers, in particular to a manufacturing process of a front-stage amplification module of a Ku-band 40-watt power amplifier. Background technique [0002] The Ku-band power amplifier refers to a power amplifier whose operating frequency is in the range of 12-18GHz. The Ku-band 40-watt power amplifier is widely used in the field of satellite communication to increase the transmission power of satellite downlink signals, expand the coverage of satellite signals, and improve communication quality. It can also be used in radar, electronic warfare and other systems. The pre-amplification module of the Ku-band 40-watt power amplifier is an important part of the Ku-band 40-watt continuous wave linear power amplifier. The quality of its indicators directly affects the parameters of the Ku-band 40-watt continuous wave linear power amplifier. [0003] The manufacturing process of the prea...
