Abstract
A Ku-band GaAs Linearizer Preamplifier Front End (LFE) has been developed for satellite TWT-amplifiers. The LFE is build in hybrid and pseudomorphic HFET MMIC technology. A variable gain MMIC amplifier, two medium power amplifier MMICs, and a power amplifier MMIC are integrated in the Front End. The LFE has been integrated with the short traveling wave tube (STWT). An improvement of 10 dB in the 3rd order intermodulation distance was measured for the LFE/TWT-system.
