Agilent WS2111
4 x 4 Power Amplifier Module
for UMTS850 (824 – 849 MHz)
Data Sheet
Description
The WS2111, a Wide-band Code
Division Multiple Access
(WCDMA) Power Amplifier (PA),
is a fully matched 10-pin surface
mount module developed for
WCDMA handset applications.
This power amplifier module
operates in the 824–849 MHz
bandwidth. The WS2111 meets
the stringent WCDMA linearity
requirements for output power of
up to 28 dBm. A low current
(Vcont) pin is provided for high
efficiency improvement of the
low output power range.
The WS2111 features CoolPAM
Circuit technology offering state-
of-the-art reliability, temperature
stability and ruggedness.
The WS2111 is self contained,
incorporating 50ohm input and
output matching networks.
Features
• CoolPAM circuit technology
• Good linearity
• High efficiency
• 10-pin surface mounting package
(4 mm x 4 mm x 1.4 mm)
• Low power-state control
• Internal 50matching networks
for both RF input and output
• Low quiescent current
Applications
• W-CDMA Handsets
• HSDPA Handsets

Notes:
1. No damage assuming only one parameter is set at limit at a time with all other parameters set at
or below nominal value.
2. High ( 1.5V 3.0V), Low (0.0V 0.5V).
3. To change between High Power Mode and Low Power Mode, switch Vcont accordingly.
4. In order to shut down the module, turn off Vref accordingly.

Notes:
1. Electrical characteristics are specified under HSDPA modulated Up-Link signal (DPCCH/DPDCH=12/15, HS-DPCCH/DPDCH=15/15) unless specified
otherwise.
2. Specified under WCDMA modulated (3GPP Uplink DPCCH + 1DPDCH) signal.
3. Control current when series 6.2kohm is used.
4. ACP is expressed as a ratio of total adjacent power to signal power, both with 3.84 MHz bandwidth at specified offsets.
