	The VSL3616 GaN SSPA is a 1.3 GHz, 700 watt CW, liquid-cooled solid state power amplifier (SSPA). It has exceptional amplitude and phase stability and is being used to drive the VKL9130A1 IOT in CPI’s VIL410 30 kW CW IOT transmitter. The VSL3616 SSPA is configured in a 19 inch rack mount enclosure. Higher power levels can be obtained by power combining multiple VSL3616 SSPAs. The VSL3616 SSPA has been designed for very tight amplitude and phase control. The amplitude ripple and phase ripple are specified to be better than 0.05% rms and better than 0.2 degrees rms, respectively. The stability of the output power is specified to be better than 0.1% over any 20 second period of time. This paper will describe the design and operation of the VSL3616 SSPA. Results from a 1000 hour life test will be presented.

	The VIL10 Heatwave™ Inductive Output Tube (IOT) amplifier system has been developed to meet the requirements of superconducting RF accelerators. Two VIL410 systems were completed and delivered in April 2014. The VKL9130A1 IOT in the VIL410 provides up to 30 kW RF output power over a 5 MHz bandwidth centered at 1.30 GHz. It operates both CW and pulsed. The VIL410 amplifier has been designed to achieve very tight amplitude and phase control. The amplitude and phase ripple are specified to be better than 0.1% rms and better than 0.2 degrees rms, respectively. The stability of the output power is specified to be better than 0.2% over a 20 second period. In normal operation, smooth control of the output is accomplished via RF input from the low level system. The VIL410 uses CPI’s VSL3616 solid state power amplifier (SSPA) to drive the IOT. The VSL3616 is a 700 watt CW SSPA which operates at 250 watts CW in the VIL410. The VIL410 has an embedded processor that controls all internal functions of the amplifier system and interfaces directly to EPICS. The VIL410 can be operated locally using a LabView PC Host program or remotely by EPICS.
