    (GaAs FETs). With Third-Order Intermodulation products from 4 to 6 dB better than TWT ratings, the Comtech EF Data unit replaces TWTs with saturated power levels of up to twice the KPA’s rated output. These KPAs also provide a Mean Time Between Failure (MTBF) that is 4 to 5 times greater than the typical TWT MTBFs.
