Pin Descriptions
PIN NUMBER
NAME
DESCRIPTION
1
TX_PE
Power enable control input. HIGH for normal operation. LOW for power down.
2
GND
Bias and AGC control ground return.
3
TXI+
Positive I channel baseband input. Requires a 1.2VDC common mode bias voltage.
4
TXI-
Negative I channel baseband input. Requires a 1.2VDC common mode bias voltage.
5
NC
No connect pin. Tie to ground to improve isolation from I to Q channels.
6
TXQ-
Negative QI channel baseband input. Requires a 1.2VDC common mode bias voltage.
7
TXQ+
Positive Q channel baseband input. Requires a 1.2VDC common mode bias voltage.
8
MIX_GND
Quadrature Mixers ground return.
9
DPS_GND
Digital Phase shifter ground return.
10
DPS_V

14
AGC_GND
AGC circuit ground return.
15
TX_IF+
Positive IF output port. Requires a DC return to V
CC
thru a choke or match inductor.
16
TX_IF-
Negative IF output port. Requires a DC return to V
CC
thru a choke or match inductor.
17
