Technical Data
HPMX-2005
Description
Plastic SO-16 Package
Features
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,incombinationwith
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.

The HPMX-2005 is fabricated with
Hewlett-Packard’s 25 GHz
0°
ISOSAT-II process, which com-
bines stepper lithography, self-
alignment, ion-implantation
techniques, and gold metallization
to produce state of the art RFICs.
