This amplifier utilizes GaN transistors to provide high gain, high efficiency and excellent frequency and amplitude stability for accelerator requirements at 500 W, CW output power. The result is excellent AM/PM and phase -noise performance. The amplifier is protected from damage by any mismatch load conditions by a ferrite isolator. The VSL3616 is optimized for operation at 1.3 GHz as an RF driver for particle accelerator operation but is usable over 1.2 - 1.4 GHz with reduced specifications. Applications: • Scientific applications The amplifier tolerates a wide temperature and cooling range with safe operation and is self protecting; but for best stability the cooling water needs to be non-varying. *The VSL3616, CPI’s 1.3 GHz, 700 Watt CW, GaN Solid State Power Amplifier, in Proceedings of Fifth International Particle Accelerator Conference, 2014 •• Solid Power Amplifiers Amplifiers• •Integrated IntegratedMicrowave Microwave Assemblies Solid State State Power Assemblies ••Receiver ControlComponents Components• •Transmitters Transmitters • Amplifiers Receiver Protectors Protectors •• Control • Amplifiers •• Modulators Magnetrons• •Crossed CrossedField FieldAmplifiers Amplifiers Modulators •• Magnetrons • Ring Loop Loop Traveling TravelingWave WaveTubes Tubes• •Power PowerCouplers Couplers Beverly Microwave Division www.cpii.com/bmd 1.3 GHz GaN Solid State Power Amplifier - VSL3616 Electrical, Mechanical and Environmental Specifications Electrical Specifications at 500 W CW Frequency Range 1.294 to 1.306 GHz Reduced Specification Frequency Range Saturated RF Output 1.2 to 1.4 GHz 500W CW 700W saturated CW Duty Cycle Power Gain 57 dB minimum 60 dB typical ± 0.2 dB Output Power Flatness across frequency range Maximum Input VSWR 1.2:1 Maximum Output VSWR Maximum Harmonic Output Minimum SNR 12:1 -35 dBc -70 dBc -105 dBc typical -65 dBc Minimum In-Band Spurious Amplitude Stability Prime Power 240VAC @ 8.0 amps Ambient Temperature Relative Humidity 95% Non-Condensing Altitude 10,000 ft.
