RADAR FRONT ENDs MIL SERIES

 

Radar Front Ends Mil RFE Series is a versatile platform configurable to handle a wide microwave frequency range and variable pulse duty cycle/ P.R.F., ideal for scientific research and fast prototypes development.
It can be delivered with various configurations, by including and internal RF pulsed source or by using an external customer source. Its transmitter section can install SSPA and TWTA amplifiers, depending from the customer specifications.
The receiver architecture features variable phase coherent gain amplifiers and can be delivered by using traditional frequency conversion system (heterodyne) or SDR direct amplifiers.
All functions are controlled by an internal sophisticated logic circuit, allowing safe operations, consumption and diagnostic monitoring, parameters setting and remote control by serial interface.
