General Description
Mimix Broadband
's 32.0-46.0 GHz GaAs MMIC
fundamental balanced mixer has been optimized for use
as a down-converter. The device has a conversion loss of
7.0 dB with a +24.0 dBm input third order intercept point.
This MMIC uses Mimix Broadband
's 0.15 m GaAs PHEMT
device model technology, and is based upon electron
beam lithography to ensure high repeatability and
uniformity. The chip has surface passivation to protect
and provide a rugged part with backside via holes and
gold metallization to allow either a conductive epoxy or
eutectic solder die attach process. This device is well
suited for Millimeter-wave Point-to-Point Radio, LMDS,
SATCOM and VSAT applications.

App Note [1] Biasing - As shown in the bonding
diagram, the pHEMT mixer devices are operated using a
separate gate voltage Vg1. Set Vg1=-0.6V for optimum
conversion loss performance. pHEMT test device (Vd,Vg2)
with 100 Ohm resistor is provided so that mixer gate bias
can be corrected for local V
to
.
App Note [2] Bias Arrangement - Each DC pad (Vg1)
needs to have DC bypass capacitance (~100-200 pF) as
close to the device as possible. Additional DC bypass
capacitance (~0.01 uF) is also recommended.
