CPI T5CI 750 W C-Band TouchPower Indoor TWTA

CPI T5CI 750 W C-Band TouchPower Indoor TWTA

The CPI T5CI is a 750 W C-band TouchPower indoor traveling wave tube amplifier designed for wideband satellite uplink applications. Covering 5.850–6.725 GHz, it delivers at least 665 W of saturated CW output power at the flange in a compact 5RU rack-mount package. Its touchscreen interface provides amplifier and system-level control, fault logs, parameter trending and performance monitoring.
