General information:

RF power amplifier printed circuit boards:

RF power amplifier (RF PA) is an important part of a variety of wireless transmitters. In the former circuit of the transmitter, the modulation signal generated by the oscillation circuit power is very small, need to go through a series of amplifying a buffer stage, the middle amplifier stage, the final power amplifier stage, get enough RF power to feed To the antenna radiation out. In order to obtain a sufficiently large RF output power, an RF power amplifier must be used.

RF power amplifier pcb play an important part in the RF power amplifier.

We have more than 7 years in HIGH FREQUENCY PCB field, power amplifier printed circuit boards are our main products

If you have any relative pcb case,can feel free to send requirements to our factory,we have professional engineer to deal with it

RF power amplifier operating frequency is high, but the relative frequency band is narrow, RF power amplifiers are generally used as the load-frequency network load circuit. RF power amplifier can be divided according to the current conduction angle, A , B , C three working conditions. Class A amplifier current conduction angle of 360 °, suitable for small-signal low-power amplifier, Class B amplifier current conduction angle is equal to 180 °, Class C current conduction angle is less than 180 °. Class B and Class C are suitable for high-power working conditions, Class C working state of the output power and efficiency is the highest of the three working conditions. RF power amplifier mostly works in Class C, but the current waveform distortion of Class C amplifier is too large, can only be used for the use of tuned loop as the load resonance power amplification. As the tuning circuit with filtering capability, loop current and voltage is still close to the sine wave, the distortion is small.
