7. Functional description
7.1 Low-noise RF ampli鏗乪r
The Low Noise Ampli鏗乪r (LNA) input impedance together with the LC RF input circuit
de鏗乶es an FM band 鏗乴ter. The gain of the LNA is controlled by the RF AGC circuit.
7.2 FM mixer
The FM quadrature mixer converts the FM RF (76 MHz to 108 MHz) to an IF of 225 kHz.
7.3 VCO
The varactor tuned LC VCO provides the Local Oscillator (LO) signal for the FM
quadrature mixer. The VCO frequency range is 150 MHz to 217 MHz.
