Function and Application
12 GND
0
–
Ground pin for modulator, up-
converter and AGC circuits. This pin
should be grounded with minimum
inductance. Form the ground
pattern as widely as possible to
minimize ground impedance.
13 LO2in

14 LO2inb
–
1.8
Local signal input for modulator.
This pin must be coupled with DC
cut capacitor 33 pF and should be
terminated with 51 Ω resistor.
1.8
Bypass pin of up-converter’s local
signal input. This pin should be
decoupled with 33 pF capacitor.

–
This pin is not connected to internal
circuit. This pin should be opened
or grounded.
16 GND
0
–
Ground pin for modulator, up-
converter and AGC circuits. This pin
should be grounded with minimum
inductance.
17 VPS/VAGC VPS/VAGC
–
Power save control pin for
modulator, up-converter and AGC
circuits. This pin also assigned as
gain control pin for AGC circuits.
Operation status with applied
voltages are as follows.
