Overview
The CPI VZK-6901J1 K-band mmWave High Power Amplifier split mount configuration provides for direct feed mounting to minimize waveguide RF losses over the entire 18 to 26.5 GHz frequency range. The power supply maintains the convenience of a rack mounted unit with built-in monitors and controls located up to 12 meters away.
