Mimix Broadband
's 19.0-26.0 GHz GaAs packaged receiver has a
noise figure of 3.0 dB and 20.0 dB image rejection across the band.
This device is a two stage balanced LNA followed by an image reject
sub-harmonic anti-parallel diode mixer and includes an integrated
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 a sub-harmonic mixer 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 device 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 device comes in a 7x7 mm QFN Surface Mount
Laminate Package offering excellent RF and thermal properties and
is RoHS compliant. This device is well suited for Millimeter-wave
Point-to-Point Radio, LMDS, SATCOM and VSAT applications.

App Note [1] Biasing
- The device is operated by separately biasing Vd1 and Vd2 with Vd1=4.0V, Id1=130mA and
Vd2=4.0V, Id2=116mA. 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.

Handling and Assembly Information
CAUTION!
- Mimix Broadband MMIC Products contain gallium arsenide (GaAs) which can be hazardous to the human body and the
environment. For safety, observe the following procedures:
Do not ingest.
Do not alter the form of this product into a gas, powder, or liquid through burning, crushing, or chemical processing as these
by-products are dangerous to the human body if inhaled, ingested, or swallowed.
Observe government laws and company regulations when discarding this product. This product must be discarded in
accordance with methods specified by applicable hazardous waste procedures.
Life Support Policy - Mimix Broadband's products are not authorized for use as critical components in life support devices or
systems without the express written approval of the President and General Counsel of Mimix Broadband. As used herein: (1) Life
support devices or systems are devices or systems which, (a) are intended for surgical implant into the body, or (b) support or sustain
life, and whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be
reasonably expected to result in a significant injury to the user. (2) A critical component is any component of a life support device or
system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its
safety or effectiveness.
Package Attachment - This packaged product from Mimix Broadband is provided as a rugged surface mount package compatible
with high volume solder installation. The package is a low-cost plastic package. Vacuum tools or other suitable pick and place
equipment may be used to pick and place this part. Care should be taken to ensure that there are no voids or gaps in the solder
connection so that good RF, DC and ground connections are maintained. Voids or gaps can eventually lead not only to RF
performance degradation, but reduced reliability and life of the product due to thermal stress.
Mimix Lead-Free RoHS Compliant Program - Mimix has an active program in place to meet customer and governmental
requirements for eliminating lead (Pb) and other environmentally hazardous materials from our products. All Mimix RoHS compliant
