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:
5. TswhighDC, TswlowDC is time required to reach stable quiescent bias (10%) after Vcont is switched low and high, respectively.
TswhighRF, TswlowRF is time required to reach final output power (±1dB) after Vcont is switched low and high, respectively.
TonDC is time required to reach stable quiescent bias (10%) after Vref is switched high.
6. ToffDC is time required for the current to be less than 10% of the Iq after Vref is switched low.
TonRF is time required to reach final output power (±1dB) after Vref is switched high.
ToffRF is time required to output power to drop 30 dB after Vref is switched low.
