Description
Hewlett Packard鈥檚 HPMX-2003 is a
Silicon RFIC direct conversion
vector modulator designed for use
at output frequencies between
800 MHz and 1 GHz. Housed in a
SO-16 surface mount plastic pack-
age, the IC contains two matched
Gilbert cell mixers, an RC phase
shifter, a summer, and an output
amplifier complete with 50
鈩?/div>
impedance match and DC block.
This device is suitable for use in
direct and offset-loop modulated
portable and mobile telephone
handsets for cellular systems such
as GSM, North American Digital
Cellular and Japan Digital Cellu-
lar. It can also be used in digital
transmitters operating in the
900 MHz ISM (Industrial-Scien-
tific-Medical) band, including use
in Local Area Networks (LANs).
The HPMX-2003 is fabricated with
Hewlett-Packard鈥檚 25 GHz
ISOSAT-II process, which
combines stepper lithography,
ion-implantation, self-alignment
techniques, and gold metallization
to produce RFICs with superior
performance, uniformity and
reliability.
