Initially developed for radar systems,
the power supplies in Quarterwave amplifiers were designed using
patented technology to provide the quietest RF amplification without
introducing spurious signals. Unlike flyback and feed forward circuits,
these solid state quasi-resonant switch mode supplies operate
without high power square waves. This results in less EMI/RFI which is amplified
by the TWT, and greater reliability due to reduced stress to the magnetic and
Control and Monitor:
All TWT voltage and current parameters are monitored
at all times by a microprocessor operating at TWT cathode
potential- as great as -15kv. The microprocessor protects
the TWT by insuring that the voltages and currents are within
limits to those stored in it's non-volatile memory. In the event
of a fault, the condition that created the fault, along with the
status and analog measurements of all TWT monitored voltages and
currents at the time of the fault, are latched into memory until
cleared by the operator. The state of the voltages and currents
along with the analog readings is sent to another microprocessor
operating at ground potential, which, along with information from
other controls and sensors, communicates via standard RS232 interface
to any external personal computer.
The Service Manual provided by Quarterwave
on all products is exceptional. Overview, Configuration, Theory
of Operation, and Modular sections provide understanding to those
unfamiliar with high performance, high voltage supplies. Block
Diagrams, Schematics, Circuit Descriptions, and Bills of Material
are complete. Colored sections and photographs provide easy orientation
and a level of sophistication not found in this industry.
