CPI T9UI 1.25 kW Ku-Band TouchPower Indoor TWTA

CPI T9UI 1.25 kW Ku-Band TouchPower Indoor TWTA

The CPI T9UI is a 1.25 kW Ku-band TouchPower indoor traveling wave tube amplifier for high-power satellite uplinks. Covering 13.75–14.50 GHz, it delivers 1,100 W of saturated CW output power at the flange and 540 W of linear multicarrier power. The compact 9RU rack-mount amplifier combines an integral linearizer with touchscreen system control and comprehensive Ethernet, serial and USB connectivity.
