A High Power Compact X-Band RF Front-End
A high-power compact RF front-end benefits from a novel high efficiency GaN SSPA with 900 W peak power, a low noise receiver, and a low noise fast switching local oscillator. Circuits for accurate calibration of both the transmit and receive channels are provided. The front-end hardware is fitted into a standard 19”, 4U enclosure.
- High both peak and average output power
- All solid state design
- High sensitivity
- High dynamic range
- Low noise local oscillator allowing accurate spectral measurements
- Decent calibration and self-test capabilities
- Compact, low weight design allowing development of portable systems
- Proved value for practical applications
