Mimix Broadband's 7.5-22.5/15.0-45.0 GHz SMD active
doubler delivers + 17 dBm of output power. The
device combines an active doubler with an output
buffer amplifier that delivers constant power over a
range of input powers. The device has excellent
rejection of the fundamental and harmonic products
and requires a single positive bias supply. This device
uses Mimix Broadband's 0.15 GaAs pHEMT device
model technology to ensure high reliability and
uniformity. The device comes in a low-cost 3x3mm
QFN Surface Mount Plastic Package offering excellent
RF and thermal properties and is RoHS compliant. This
device is well suited for Point-to-Point Radio,
Microwave, LMDS, SATCOM and VSAT applications.

7.5-22.5/15.0-45.0 GHz Active Doubler
QFN, 3x3 mm
App Note [1] Biasing - It is recommended to separately bias each doubler stage with Vd(1,2)=5.0V with Id1=80mA and Id2=140mA
and Vss=-5.0V with Iss=50mA. XX1000-QT provides good performance at reduced bias with Vss=-2.0V and Iss=25mA. Maximum
output power is achieved with Vss=-5.0V and Iss=50mA. Separate biasing is recommended if the doubler is to be used at high levels
of saturation, where gate rectification will alter the effective gate control voltage. 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 voltages needed to do this are Vg1=-0.6V and Vg2=0.0V.
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
components are form, fit and functional replacements for their non-RoHS equivalents. Lead plating of our RoHS compliant parts is
100% matt tin (Sn) over copper alloy and is backwards compatible with current standard SnPb low-temperature reflow processes as
well as higher temperature (260°C reflow) “Pb Free” processes.
