About the LNA
This LNA is intended for the satellite communication data downlink application in C-band. It is combined a 3-stage HEMT amplifier. The LNA receives an RF signal (C-band: 3.4 to 4.2 GHz, or 4.5 to 4.8 GHz) as input, amplifies and outputs the RF signal. It is operated by +24 V DC power (range: +12 to +28 V) input. The LNA comes in a single, weatherized housing rated for outdoor use, and has a CPR-229G waveguide flange as RF input and an N-type female connector as RF output.
