RF Transceiver

Alico Systems has developed a unique multi-functional transceiver that provides up/down conversion, digital beacon detector and back end interface options that include either a L-band IF interface or a digital interface based on LVDS. The transceiver is based on a 2 board printed circuit board assembly shown below which includes the blue color RF module and green color digital controller. RF module is shielded on the top and bottom.
