CC
Keyed AGC input
Since the DC cut capacitor is provided on-chip in the
pin internal circuit, we have taken steps to prevent
incorrect AGC operation due to inter-pin leakage
currents.
IF gain: 25 dB
Input and output impedances of 330
The IF gain can be adjusted by inserting a resistor
between pins 17 and 19.
The gain is at its maximum when there is no resistor
inserted.
MOSFET
Second gate control
Controls the narrow AGC.
