Working Principles

The MAX703CSA-T operates based on the principle of FSK modulation. It receives digital data from the TXD pin, modulates it into an RF signal, and transmits it through the antenna connection (ANT). On the receiving side, it detects the incoming RF signal, demodulates it, and outputs the received data through the RXD pin. The AGC feature helps maintain optimal signal strength and improve overall performance.
