Connecting a nonpolarity capacitor of 1 F between pin 14 and pin 18 improves AGC operating
speed.
In that case, the capacitors between pin 14/pin 18 and ground should be removed.

A current mode output is available in the reverse AGC
operation.
(V14)
It is GND pin except for SIF.
It should be designed considering careful impedance
matching with the SAW filter.
An applied voltage to the pin 18 is for changing a RF AGC
delay point.
In the 3-in-1 type application, the regulated output from the
regulator is suitable for a power supply (V
