Product details
The CPI TL12DO-A1 is a 1250W DBS-Band air-cooled SuperLinear outdoor TWTA. It's rated 1250W peak from the TWT (1100W at the flange) and guarantees 552W CW at the flange (700W max.) across 17.3–18.4 GHz, with 1100 MHz of bandwidth.
Optimized for efficiency at linear operating levels, it achieves NPR of -19 dBc at 440W with the optional linearizer. It runs on 208–240 VAC single phase (2.8 kVA typical) and weighs 95 lb.
