HPMX-2006

The HPMX-2006 upconverter/ amplifier IC is designed to meet the needs of cellular and PCS telephone and wireless LANapplications.

The HPMX-2006 consists of a Gilbert Cell mixer optimized for upconversion followed by a post-amplifier. The mixer and amplifier are independent allowing the insertion of a sideband filter between the two.

The HPMX-2006 mixer is double balanced. Both LO and IF inputs may be run either single-endedly, or in differential mode to reduce LO leakage. LO inputs are matchednear 50 W; high impedance IF inputs allow the mixer to be usedas a BPSK modulator. An integratedtransformer on the mixer RF port creates a single-ended, matched to 50 W output at1900 MHz, and also reduces common mode noise.

The amplifier features a singleended 50 W match on the input port. The open collector output is easily matched with a simple 2 element network, providing flexible use and good power added efficiency. The amplifier can be disabled to allow use of the mixer alone, reducing the current draw to around 15 mA. The entire IC can be put into a standby mode reducing current consumption to under 40 mA from a 3V source. The SSOP-16 package insures that HPMX-2006 occupies a minimal amount of printed circuit board space.

The HPMX-2006 is manufactured using Hewlett-Packard's 30 GHz ISOSAT-II process which combines stepper lithography, self alignment, ion implantation techniques and gold metalization to produce state-of-the-art RFICs.
