Continued from preceding page.

Pin No.

Function

13 N-AGC input

LA1193M, 1193V

Equivalent circuit

Note

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.

14 IF AMP bypass

15 IF AMP input

18 IF AMP output

19 IF AMP gain adjust

IF gain: 25 dB

Input and output impedances of 330 Ω

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.

16 RF AGC output

17

IF, AGC, VCC

20 Keyed AGC input

MOSFET

Second gate control

Controls the narrow AGC.

No. 4715-7/21
