Input IP3: Up to +17 dBm
Sub-Harmonically Pumped (x2) LO
Small Size: 1.32mm x 1.47mm
General Description
The HMC266 chip is a broadband GaAs MMIC
sub-harmonically pumped (x2) balanced passive
mixer which can be used as an upconverter or
downconverter in a small overall chip area of 1.9
mm2. The 2LO to RF isolation is excellent elimi-
nating the need for additional filtering. All data is
with the chip in a 50 ohm test fixture connected
via 0.076 mm (3 mil) ribbon bonds of minimal
length <0.31 mm (<12 mils). These devices are
much smaller and more reliable than hybrid diode
mixer designs.

Mounting & Bonding Techniques for Millimeterwave GaAs MMICs
The die should be attached directly to the ground plane eutectically or with conductive epoxy (see HMC general Handling, Mounting,
Bonding Note).
50 Ohm Microstrip transmission lines on 0.127mm (5 mil) thick alumina thin film substrates are recommended for bringing RF to and
from the chip (Figure 1). If 0.254mm (10 mil) thick alumina thin film substrates must be used, the die should be raised 0.150mm (6
mils) so that the surface of the die is coplanar with the surface of the substrate. One way to accomplish this is to attach the 0.102mm (4
mil) thick die to a 0.150mm (6 mil) thick molybdenum heat spreader (moly-tab) which is then attached to the ground plane (Figure 2).
Microstrip substrates should be brought as close to the die as possible in order to minimize bond wire length. Typical die-to-substrate
spacing is 0.076mm (3 mils). Gold ribbon of 0.076 mm x 0.013 mm (3 mil x 0.5 mil) of minimal length <0.31 mm (<12 mils) is recom-
mended to minimize inductance on the RF ports.
