WPA Series High Power Amplifiers

WPA series high power amplifiers have high power with exceptional linearity based on HFF [1] technology. The amplifiers offer IP3 of from 50 dBc to 70 dBc with higher efficiency than traditional Feed Forward Amplifier (FFA). However, the cost of a WPA is a small fraction of a traditional FFA. Moreover, the circuitry is much simpler than that of the FFA. The linearity is better than that of any pre-distortion PA.
