CPI TL05KO-L1 550 W Ka-Band Liquid-Cooled Outdoor TWTA

CPI TL05KO-L1 550 W Ka-Band Liquid-Cooled Outdoor TWTA

The CPI TL05KO-L1 is a compact, weatherproof 550 W peak Ka-band liquid-cooled traveling wave tube amplifier for wideband single- and multicarrier satellite uplinks. It supports up to 4 GHz of instantaneous bandwidth within 27.0–31.0 GHz and provides up to 420 W CW or 257 W linear output power at the flange. Liquid cooling eliminates the need for internal cooling fans, making it ideal for fixed earth stations requiring quiet, efficient operation.
