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, 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 W using a shunt L, series C network. Alternatively, the output can be matched to 50 W 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.
