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.
