| 25th April 2005 - Agilent
Technologies Inc. today announced its family of
4 mm by 4 mm power amplifier (PA) modules featuring
CoolPAM technology. CoolPAM significantly reduces
battery power consumption and allows mobile handsets
to run cooler.
Agilent’s CoolPAM technology uses advanced
InGaP (indium gallium arsenide) HBT (heterojunction
bipolar transistor) MMIC (microwave monolithic
integrated circuit) technology to provide state-of-the-art
reliability, temperature stability, cool operation
and ruggedness. CoolPAM power amplifiers are already
proven in handsets from leading manufacturers
in Korea.

“Now Agilent offers handset manufacturers the
choice of power amplifiers featuring E-pHEMT technology
for the industry’s highest power-added efficiencies
and InGaP HBT technology that provide the industry’s
lowest average power consumption,” said Bryan Ingram,
vice president and general manager of the Wireless Semiconductor
Division in Agilent’s Semiconductor Products Group.
“CoolPAM technology will be integrated into next-generation
front-end modules that incorporate low-loss FBAR duplexers
to dramatically extend the talk time of mobile handsets.”
The CoolPAM product line offers three versions of W-CDMA
(wideband code division multiple access) power amplifier
modules:
The WS2512 operates in the UMTS (Universal Mobile Telecommunications
System) 2100 (1920 to 1980 MHz) frequency range for
CDMA (code division multiple access) and W-CDMA handsets.
UMTS2100 is a third-generation (3G) standard for regions
of Europe and Asia that use GSM (Global System for Mobile
Communications).
The WS2512 meets the stringent High-Speed Downlink Packet
Access (HSDPA) linearity requirements for an output
power of up to +27 dBm. In low-power mode in conjunction
with a DC-DC converter, performance is 13 percent at
+7 dBm output power with 8 mA quiescent current.
The WS2411 operates in the UMTS1900 (1850-1910 MHz)
frequency range. Used in the Americas and the Caribbean,
it meets HSDPA linearity requirements for output power
of up to +28.5 dBm. In low-power mode in conjunction
with a DC-DC converter, performance is 11 percent at
+7 dBm output power with 13 mA quiescent current.
The WS2111 operates in the cellular band (824 to 849
MHz) and meets HSDPA linearity requirements at output
power levels up to 27.5 dBm. In low-power mode in conjunction
with a DC-DC converter, performance is 11 percent at
+7 dBm output power with 10 mA quiescent current.
All versions of the CoolPAM W-CDMA product line can
operate at 3.2 to 4.2 volts for compatibility with today’s
low-current consumption designs. They all incorporate
50-ohm input and output matching networks for simple
integration, and are equipped with a control pin that
sets operating parameters for highest efficiency when
operating at low-output power levels. The new PAs offer
the lowest average operating current in the industry.
All versions are compatible with HSDPA, a packet-based
data service providing data transmission at up to 10
Mb/s, and 20 Mb/s for MIMO (multiple-input multiple-output)
systems over a 5 MHz bandwidth.
The CoolPAM W-CDMA devices are supplied in a 4 mm x
4 mm x 1.4 mm, 10-pin surface-mount module designed
to assure high thermal conductivity, which minimizes
temperature rise for higher reliability. All versions
are fabricated with an advanced InGaP HBT MMIC technology
offering state-of-the-art reliability, temperature stability
and ruggedness.
