Chip Device Layout
General Description
Mimix Broadband’s 0.05-50.0 GHz GaAs MMIC
distributed amplifier has a small signal gain of 9.0 dB
with a noise figure of 5.0 dB across the band.The
device also includes 15.0 dB gain control and a +9.0
dBm P1dB compression point.This MMIC uses Mimix
Broadband’s 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 microwave,
millimeter-wave and wideband military applications.

D1002-BD
App Note [1] Biasing - As shown in the bonding diagram, this
device is operated with a single drain and gate voltage and it also
includes a separate gain control voltage. Maximum gain bias is
nominally Vd=8.5V, Vg1=0.0V, Vg2=1.0V, and Id=120mA. Gain can be
adjusted by changing Vg1. It is 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 0.0V.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 Vg1,2) need 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.
