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
–
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.
14
LO2inb
–
1.8
Bypass pin of up-converter’s local
signal input. This pin should be
decoupled with 33 pF capacitor.

–
Ground pin for modulator, up-
converter and AGC circuits. This pin
should be grounded with minimum
inductance.
–––––––––––––––––
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.
