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
regulated 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
μ
A, 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 5x5mm 32 pin TQFP package.
