Mimix Broadband’s 17.0-27.0 GHz GaAs MMIC receiver has a small signal
conversion gain of 10.0 dB with a noise figure of 3.5 dB and 15.0 dB
image rejection across the band. The device is a three stage LNA
followed by an image reject fundamental mixer using Lange couplers to
improve bandwidth. The image reject mixer eliminates the need for a
bandpass filter after the LNA to remove thermal noise at the image
frequency. I and Q mixer outputs are provided and an external 90
degree hybrid is required to select the desired sideband. This MMIC uses
Mimix Broadband’s 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 is operated with all three stages in
parallel, and can be biased for low noise performance or high power performance. Low noise bias is
nominally Vd=3V, Id=90mA and is the recommended bias condition. Power bias may be as high as
Vd=5.5V, Id=180mA. 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.
