Overview
The CPI VZA-6902J1 Ka-band Millimeter Wave Power Amplifier split mount configuration provides for direct feed mounting to minimize waveguide RF losses over the entire 26.5 to 40.0 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.
