Description
Hewlett Packard’s HPMX-2005 is a
silicon RFIC vector modulator
housed in a SO-16 surface mount
plastic package. This IC can be
used for direct modulation at out-
put frequencies from 25 to
250␣ MHz, or, in combination with
an up-converting mixer, for dual
or multiple conversion modula-
tion to higher frequencies. The IC
contains two matched Gilbert cell
mixers, an RC phase shifter, a
summer, and an output amplifier.
This RFIC is well suited to por-
table and mobile cellular tele-
phone applications such as North
American Digital Cellular, GSM,
and Japan Digital Cellular, and to
Personal Communications Sys-
tems such as DCS-1800 or
handyphones. It is also useful for
applications in 900 MHz, 2.4 GHz
and 5.7 GHz ISM (Industrial-Scien-
tific-Medical) bands requiring digi-
tal modulation, such as Local Area
Networks (LANs).
The HPMX-2005 is fabricated with
Hewlett-Packard’s 25 GHz
ISOSAT-II process, which com-
bines stepper lithography, self-
alignment, ion-implantation
techniques, and gold metallization
to produce state of the art RFICs.
