App Note [1] Biasing - It is recommended to bias the amplifier with Vd=4.0V and IdTOTAL=250mA. 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 Each DC pin (Vd and Vg) needs to have DC bypass capacitance (100pF/10nF/1uF) as close to the package as possible.

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 byproducts 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. 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.
