P1042-QT
The XP1042-QT is a packaged driver amplifier that
operates over the 12.0-16.0 GHz frequency band. The
device provides 21 dB gain and 38 dBm Output Third
Order Intercept Point (OIP3) across the band and is
offered in an industry standard, fully molded 3x3mm
QFN package. The device includes on-chip ESD
protection structures and DC by-pass capacitors to
ease the implementation and volume assembly of the
packaged part. The device is manufactured in 0.5um
GaAs PHEMT device technology with BCB wafer
coating to enhance ruggedness and repeatability of
performance. The XP1042-QT is well suited for
Point-to-Point Radio, LMDS, SATCOM and VSAT
applications.

Recommended Layout
App Note [1] Biasing - As shown in the Pin Designations table, the device is operated by biasing VD1,2,3 at 5.0V with 125, 125, 250 mA respectively.
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 -1.0V. 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.

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.
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% matte 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.
