General Description
Mimix Broadband’s 30.0-46.0 GHz GaAs MMIC receiver has a noise
figure of 3.5 dB and 18.0 dB image rejection across the band. This
device is a three stage LNA followed by an image reject resistive
pHEMT mixer and includes an integrated LO doubler and LO buffer
amplifer. The image reject mixer eliminates the need for a bandpass
filter after the LNA to remove thermal noise at the image frequency.
The use of integrated LO doubler and LO buffer amplifier makes the
provision of the LO easier than for fundamental mixers at these
frequencies. 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 by separately biasing Vd1, Vd2 and Vd3 with
Vd(1,2,3)=4.0V, Id1=Id2=25mA and Id3=145mA. Additionally, a mixer and doubler bias are also required with Vg4=Vg5=-0.5V. Adjusting Vg4
and Vg5 above or below this value can adversely affect conversion gain, image rejection and intercept point performance. 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 -0.3V. 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
-
For Parallel Stage Bias (Recommended for general applications) -- The same as Individual Stage Bias but all the drain or gate pad DC bypass
capacitors (~100-200 pF) can be combined. Additional DC bypass capacitance (~0.01 uF) is also recommended to all DC or combination (if
gate or drains are tied together) of DC bias pads.
For Individual Stage Bias -- Each DC pad (Vd1,2,3 and Vg1,2,3,4,5) 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.
