General Description
Mimix Broadbands 17.0-27.0 GHz GaAs MMIC
transmitter has a small signal conversion gain of 0.0
dB with a third order intercept of +12.0 dBm across
the band.The device is a single fundamental mixer
followed by a single stage amplifier.This MMIC uses
Mimix Broadbands 0.15 µm 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, this device has a single gain stage. Nominal bias is
Vd=3V, Id=23mA. Power bias may be as high as Vd=5.5V, Id=45mA. It is also recommended to use active
biasing to keep the currents constant as the RF power and temperature vary; this gives the most reproducible
results. Depending on the supply voltage available and the power dissipation constraints, the bias circuit
may be a single transistor or a low power operational amplifier, with a low value resistor in series with the
drain supply used to sense the current.The gate of the pHEMT is controlled to maintain correct drain current
and thus drain voltage.The typical gate voltage needed to do this is -0.5V.Typically the gate is protected with
Silicon diodes to limit the applied voltage. Also, make sure to sequence the applied voltage to ensure
negative gate bias is available before applying the positive drain supply.
App Note [2] Bias Arrangement - Each DC pad (Vd and Vg) 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.
