FM RADIO TUNER
The Si4702/03-C19’s patented digital low-IF architecture reduces external components and eliminates the need for factory adjustments. The receive(RX) section integrates a low noise amplifier (LNA)supporting the worldwide FM broadcast band (76 to 108 MHz). An automatic gain control (AGC) circuit controls the gain of the LNA to optimize sensitivity and rejection of strong interferers.
