Functional description
8.1 Low noise RF amplifier
The LNA input impedance together with the LC RF input circuit defines an FM band filter.
The gain of the LNA is controlled by the RF AGC circuit.
8.2 FM I/Q mixer
FM quadrature mixer converts FM RF (76 MHz to 108 MHz) to IF.
8.3 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.
