A GaN Solid State Amplifier Replacement for a 1kW Traveling Wave Tube

Advances in GaN transistor technology, including higher frequency, bandwidth and power, offer the opportunity to overcome TWT (Traveling Wave Tube) limitations with solid state power amplifiers (SSPA). These solid state designs overcome the inherent problems with electron tube TWTs of limited life and single point failure susceptibility while addressing the competing high performance airborne system requirements of kilowatt power levels and compact size.
