L Band Satellite Beacon Receiver, High Stability. AFC: ±60 kHz. Input Frequency: 930 MHz to 2150 MHz. Ethernet and Continuous Digital Streaming Options. Designed to real time track the power density of a satellite beacon and output a temperature stabilized DC voltage that is linearly proportional to the beacon power by utilizing a true, RMS-responding power detector. Applications: Antenna Tracking Controllers / Uplink Power Controllers / Telemetry Beacons.
