What are RF amplifiers used for?
Updated : 2022-09-19

RF amplifiers stand for radio frequency amplifiers, which usually are used to amplify a low-power RF signal into a higher power signal from a few MHz to the multi-GHz range.

What does an RF power amplifier do?
Updated : 2022-09-19

The RF power amplifier is an important part of all kinds of wireless transmitters. In the front-end circuit of the transmitter, the power of the RF signal generated by the modulation oscillator circuit is very small, and it needs to go through a series of amplification.

2GHz to 6GHz 20Watts GaN wideband power amplifier KB2060M43B
Updated : 2022-05-13

RF solid state power amplifier, which is basically the positive feedback system in our RF system, is generally located on the transmission chain. Considering the link attenuation of wireless transmission, the transmitter needs to radiate enough power to obtain a relatively long communication distance. Therefore, the radio frequency amplifier is mainly responsible fo...
