CIRCUIT DESCRIPTION (CONT.)
FM Detector:
The FM detector is included in the quadrature FM detector using a Gilbert multiplier.
It is suitable for high speed data communication because the demodulation bandwidth is over 1 MHz.
The phase shifter is connected between Pin 10 (IF limiter output) and Pin 9 (input detector). Any available phase shifter
can be used: a LC resonance circuit, a ceramic discriminator, a delay line, etc.
Figure 4 shows the internal equivalent circuit of the detector.
