Function and Application

Internal Equivalent Circuit

28 IF-MIXout



1.15

Output pin from IF mixer.

IF mixer output signal goes

through gain control amplifier

before this emitter follower

30

output port.

31

29 N.C.





Non connection

33

30 VGC (IF-MIX)

0 to 3.3



Gain control voltage pin of IF

28

mixer output amplifier. This

2nd

voltage performs forward control LO

(VGC up → Gain down).

34

31 VCC (IF-MIX) 2.7 to 3.3



Supply voltage pin of IF mixer,

gain control amplifier and

emitter follower transistor.

32 N.C.





Non connection

33 IF-MIXin



2.00

Input pin of IF mixer.

34 GND (IF-MIX)

0



Ground pin of IF mixer.

Caution Ground pattern on the board must be formed as wide as possible to minimize ground

impedance.
