Technical Details:

The TDA5200A3 utilizes a super-regenerative receiver architecture, optimized for ASK modulation. It integrates a low-noise amplifier (LNA), mixer, and demodulator within a single integrated circuit. The RSSI output provides an analog voltage proportional to the received signal strength. The device is designed to operate across a broad temperature range. Consult the Infineon datasheet for specific details regarding operating frequencies, sensitivity specifications, and power consumption characteristics. This component is commonly available in a small outline package (SOIC) to facilitate surface mounting and integration.
