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.
