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...
