Model 177 10kw TWT Amplifier
Available from Applied Systems Engineering, Inc.
The Model 177 TWT Amplifier has been designed specifically to operate pulsed traveling wave tubes up to 10 kW peak power, 5% duty cycle and at frequencies up to 18GHz. Particular emphasis has been placed on the generation of the output RF pulse shape wihtout the use of RF switches. Pulse width control is with an external pulse. Internal power supplies are DC-DC converter designs with fast loop response times so that output level variations are minimal for any PRF including a non-periodic or burst type PRF. The modular power supplies and grid pulse generator have very low ripple, with attendant low phas noise in the TWT Amplifier. The modular design of the Model 177 provides convenient accessibility to all elements in the TWT Amplifier. Plug-in PC boards are accessible through the front panel. The PC card cover contains a legend for PC card located test points and controls. High voltage modules are encapsulated, plug-in assemblies. There is not exposed high voltage. Most modules are interchangeable between all units regardless of frequency.
