General Description
The HPMX-2007 vector
modulator/mixer IC is designed to
meet the needs of cellular and
PCS telephone applications.
The heart of the IC is a vector (or
quadrature) modulator followed
by a Gilbert cell mixer. The
modulator and mixer can be used
together, drawing only 25 mA
from a 3.0 volt supply. The mixer
can be disabled by connecting
either LOmix or LOmix to VCC,
Page 2
allowing operation of the
modulator alone and reducing
current drain to only 10 mA.
The i and q signal inputs are
balanced to insure high common
mode noise rejection.
The output of the mixer is a
differential pair of open collectors.
One collector can be connected
to VCC and the other matched to
50 Ω using a shunt L, series C
network. Alternatively, the output
can be matched to 50 Ω through a
4:1 balun.
The SSOP-16 package insures that
the IC occupies a minimal amount
of printed circuit board space.
The HPMX-2007 is manufactured
using Hewlett-Packard’s 30 GHz
ISOSAT-II process which
combines stepper lithography,
self alignment, ion implantation
techniques and gold metallization
to produce state-of-the-art RFICs.
