CPI 40W KA-Band TWT Model VZK-6901J1
CPI 40W KA-Band TWT Model VZK-6901J1 is designed solely for test and measurement applications. It will generate a KA-Band RF signal in the range of 18 to 26.5 GHz with 8.5GHz bandwidth.

CPI 40W KA-Band TWT Model VZK-6901J1

The amplifier is split into two components allowing it to be used on a test bench or mounted outdoors. There are two complete sets of controller plus amplifier, but no cables. In addition there are two additional TWTAs without the controllers.
