Background

Radio frequency power amplifiers (RF PAs) are an important component of various wireless transmitters. In the front stage circuit of the transmitter, the radio frequency signal power generated by the modulation oscillation circuit is very small, and the radio frequency signal can be fed to an antenna to be radiated after sufficient radio frequency power is obtained through a series of amplifying-buffering stage, intermediate amplifying stage and final power amplifying stage. In order to obtain a sufficiently large radio frequency output power, a radio frequency power amplifier must be employed.

The operating frequency of the rf power amplifier is very high, but the frequency band is relatively narrow, and the rf power amplifier generally adopts a frequency-selective network as a load loop. The radio frequency power amplifier can be divided into three working states of A (A), B (B) and C (C) according to the difference of current conduction angles. The conduction angle of the class A amplifier is 360 degrees, the amplifier is suitable for small-signal low-power amplification, the conduction angle of the class B amplifier is equal to 180 degrees, and the conduction angle of the class C amplifier is smaller than 180 degrees. The class B and class C are both suitable for high-power working states, and the output power and the efficiency of the class C working state are the highest of the three working states.

In the production process of the radio frequency amplifier, the processor module of the radio frequency amplifier needs to be connected with the external interface, but in the existing production process, the external interface is troublesome to fix, and the corresponding mould needs to be replaced for each type of interface, so that the production is inconvenient, and the working efficiency is reduced.
