Product data sheet
7.1 Low-noise RF amplifier
7.2 FM mixer
7.3 VCO
Table 3.
The Low Noise Amplifier (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.
The FM quadrature mixer converts the FM RF (76 MHz to 108 MHz) to an IF of 225 kHz.
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.
