General Description
Mimix Broadband’s 27.5-33.4 GHz QFN packaged
receiver has a noise figure of 2.5 dB and 13.0 dB
conversion gain. The device integrates an LNA, image
reject mixer and LO buffer amplifier within a fully
molded 4x4mm QFN package. 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
device uses Mimix Broadband’s GaAs pHEMT device
model technology, and is based upon electron beam
lithography to ensure high repeatability and uniformity.
This device is well suited for Point-to-Point Radio, LMDS,
SATCOM and VSAT applications.

App Note [1] Biasing - As shown in the Pin Designations table, the device is operated by biasing VD1,2,3 at 3.0V with 7.5, 30, 90mA respectively.
Additionally, a fixed voltage bias of -3V is required for mixer bias. It is recommended to use active bias to keep the currents constant in order to
maintain the best performance over temperature. 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 -0.35V.
Make sure to sequence the applied voltage to ensure negative gate bias is available before applying the positive drain supply.
App Note [2] Board Layout - As shown in the board layout, it is recommended to provide 100pF decoupling caps as close to the bias pins as
possible, with additional 10µF decoupling caps.

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.
Electrostatic Sensitive Device Observe all necessary precautions when handling.
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. 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.
