Description
The MAGX-011086 is a GaN on silicon HEMT
amplifier optimized for DC - 6 GHz operation in a
user friendly package ideal for high bandwidth
applications. The device has been designed for
saturated and linear operation with output power
levels of 4 W (36 dBm) in an industry standard, low
inductance, surface mount QFN package. The pads
of the package form a coplanar launch that naturally
absorbs lead parasitics and features a small PCB
outline for space constrained applications.
The MAGX-011086 is ideally suited for Wireless
LAN, High Dynamic Range LNA’s, broadband
general purpose, land mobile radio, defense
communications, wireless infrastructure, and ISM
applications.
Built using the SIGANTIC® process - a proprietary
GaN-on-Silicon technology.

4. Exceeding any one or combination of these limits may cause permanent damage to this device.
5. MACOM does not recommend sustained operation near these survivability limits.
6. Operating at nominal conditions with TJ ≤ 200°C will ensure MTTF > 1 x 106 hours.
Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
Gallium Nitride Integrated Circuits are sensitive to
electrostatic discharge (ESD) and can be damaged
by static electricity. Proper ESD control techniques
should be used when handling these class 1A
devices.
Thermal Characteristics7,8
Parameter Test Conditions Symbol Typ. Units
Thermal Resistance VDS = 28 V, TJ = 200°C ӨJC 12.5 °C/W
7. Junction temperature (TJ) measured using IR Microscopy. Case temperature measured using thermocouple
embedded in heat-sink.
8. The thermal resistance of the mounting configuration must be added to the device ӨJC, for proper TJ
calculation during operation. The recommended via pattern, shown on page 6, on a 20 mil thick, 1 oz. plated
copper, PCB contributes an additional 6.6°C/W to the typical value.

Evaluation Board and Recommended Tuning Solution
5.8 GHz Narrowband Circuit
Description
Parts measured on evaluation board (20-mil thick
RO4350). The PCB’s electrical and thermal ground
is provided using a standard-plated densely packed
via hole array (see recommended via pattern).
Matching is provided using a combination of lumped
elements and transmission lines as shown in the
simplified schematic above. Recommended tuning
solution component placement, transmission lines,
and details are shown on the next page.
Bias Sequencing
Turning the device ON
1. Set VGS beyond pinch-off (VP), typically -5 V.
2. Turn on VDS to nominal voltage (28 V).
3. Increase VGS until the IDS current is reached.
4. Apply RF power to desired level.
Turning the device OFF
1. Turn the RF power off.
2. Decrease VGS down to VP.
3. Decrease VDS down to 0 V.
4. Turn off VGS.
