Features
Sub-Harmonically Pumped (x2) LO
High 2LO/RF Isolation: >35 dB
Small Size: 1.24mm x 1.55mm
General Description
The HMC259 chip is a broadband sub-harmoni-
cally pumped (x2) balanced MMIC passive mixer
which can be used as an upconverter or down-
converter. The chip utilizes a GaAs MESFET
process resulting in a small overall chip area of
1.9mm2. This chip has a very wide IF bandwidth
of DC-13 GHz. The 2LO to RF isolation is excel-
lent eliminating the need for additional filtering.
All data is with the chip in a 50 ohm test fixture
connected via 0.025mm (1 mil) diameter wire
bonds of minimal length <0.31mm (<12 mils).
This device is a much smaller and more reliable
replacement to hybrid diode mixer designs.
