12 kW Solid-state Pulse Amplifier

摘要

The Advantech Wireless model APRA-L12000A is for a 12 kW L-Band solid-state pulse amplifier operating in the band of 1.2 to 1.4 GHz. Intended for radar applications, this unit provides the peak power with a duty cycle of up to 12 percent. The unit consists of 8 X 1.8 kW modular amplifiers that are phase combined using a special high power, low loss combiner. The product was created in response to an overwhelming demand in the marketplace for robust, solid- state pulse amplifiers that can be vehicle-mounted. It can be used in military and civilian radar systems. Due to the modular architecture, a failed RF module may be safely removed and replaced without service interruption (hot-swapped). A single module failure will cause a drop of only 1.16 dB in output power. The Interface Panel containing a redundant input/driver module provides the Monitor and Control Interface for the entire system. The power supply system is also modular, operating on a load-sharing configuration with hot-swappable capability.
