Telemetry Receiver

The Receiver with Bit-Synchronizer is used to receive the RF signals from Antenna through RF Box for demodulating the data. It is a compact design and has an easy-to-use GUI for configuration and monitoring. The input signal of 2.2 GHz to 2.3 GHz initially passes through the bandpass filter and low noise amplifier. The synthesizer and mixer down convert to IF of 70 MHz, the signal passes through a bank of selectable IF filters. A Digital control attenuator along with the detected AGC is used to take care of the dynamic range.
