2) Circuit Operation
The design of the power module (PAM) provide bias
control via Vcntl to achieve optimal RF performance
and power control. The control pin is labeled Vref
(Vcntl). Please refer to Figure 26 for the block diagram
of this PAM.

The demonstration PC Board provides an adequate
heat sink. Maximum device dissipation should be
kept below 2.5 Watts.
- Signal Source
The CDMA modulated signal for the test is
generated using an Agilent Technologies ESG-
D4000A (or ESG-D3000A) Digital Signal Generator

- ACPR Measurement
The ACPR (and channel power) is measured using
an Avago Technologies 4406 VSA with
corresponding ACPR offsets for IS-98c and JSTD-8.
Averaging of 10 is used for ACPR measurements.
- DC Connection
A DC Connector is provided to allow ease of
connection to the I/O’s. Wires can be soldered to
the connector pins, or the connector can be
removed and I/O’s contacted via clip leads or direct
soldered connections. The wiring of I/O’s are listed
in Figure 1 through 3 and Pin configuration table.
The Vdd sense connections are provided to allow
the use of remote-sensing power supplies for
compensation of PCB traces and cable resistance.
- Device Operation
1) Connect RF Input and Output for the band
2) Terminate all unused RF ports into 50 Ohms.
3) Connect Vdd1 and Vdd2 supplies (including
4) Connect Vcntl supply and set reference voltage
5) Apply RF input power according to the values
6) Power down in opposite sequence.

to the voltage shown in the data packet. Note
that the Vcntl pin is on the back side of the
demonstration board. Please limit Vcntl to not
exceed the corresponding listed “DC Biasing
Condition” in the Data Packet. Note that
increasing Vcntl over the corresponding listed
“DC Biasing Condition” can result in power
decrease and current can exceed the rated limit.
