General Description
The HPMX-7201 upconverter is
designed for use in Dual-Band,
Dual-Mode PCS-CDMA/AMPS
handsets and complements
Agilent Technologies鈥檚 CDMA
Chipset solution.
The HPMX-7201 contains an
upconverter and RF variable gain
driver amplifier for the
PCS-CDMA transmit chain. The
AMPS transmit chain features an
image reject upconverter and a
driver amplifier.
The PCS-CDMA transmit chain
provides excellent Adjacent
Channel Power Rejection and a
low noise floor for compliance
with TIA98-C requirements. The
CDMA driver has a high output
power for direct interfacing with
CDMA Power Amplifiers and
incorporates a switch on the
output to support split-band
filtering. The driver is adaptively
biased to reduce current con-
sumption and extend battery life.
The image reject upconverter on
the AMPS transmit chain elimi-
nates the need for a filter between
the mixer and the driver amplifier.
The IC operates from a 3V regu-
lated supply, making it ideal for
use with a single cell Lithium Ion
battery. The Drivers can be
directly powered from the battery
for enhanced performance. The
power down function reduces the
supply current to 1
碌A(chǔ),
typical to
support gated operation and
eliminate the need for a power
supply switch.
The HPMX-7201 is fabricated
using a 40 GHz Fmax silicon
bipolar process and is packaged in
a 5x5 mm 32 pin TQFP package.
