Product Information
Product Description
Functional Diagram
The AH3 is a high dynamic range amplifier in a low-cost
surface-mount package. The combination of low noise
figure and high output IP3 at the same bias point makes it
ideal for receiver and transmitter applications. The device
combines dependable performance with superb quality to
maintain MTTF values exceeding 100 years at mounting
temperatures of +85 °C. The AH3 is available in the
environmentally-friendly lead-free/green/RoHS-compliant
SOT-89 package.

The broadband amplifier uses a high reliability GaAs
MESFET technology and is targeted for applications where
high linearity is required. In addition, the AH3 is internally
matched for 50 ohms.

1. Test conditions unless otherwise noted: T = 25 ºC, 50 Ω system.
2. 3OIP measured with two tones at an output power of +5 dBm/tone separated by 10 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
3. Noise figure can be optimized by matching the input for optimal return loss.

Product Information
AH3-G Mechanical Information
This package is lead-free/Green/RoHS-compliant. It is compatible with both lead-free (maximum 260 °C reflow temperature) and leaded
(maximum 245 °C reflow temperature) soldering processes. The plating material on the leads is NiPdAu.
Outline Drawing
Product Marking
The AH3-G will be marked with an “AH3G”
designator.
An alphanumeric lot code
(“XXXX-X”) is also marked below the part
designator on the top surface of the package.
The obsolete tin-lead package is marked with
“AH3” designator followed by alphanumeric
lot code.
Tape and reel specifications for this part are
located on the website in the “Application
Notes” section.

1. The thermal resistance is referenced from the hottest
part of the junction to the ground tab (pin 4).
2. This corresponds to the typical biasing condition of
+5V, 150 mA at an 85°C case temperature. A
minimum MTTF of 1 million hours is achieved for
junction temperatures below 160 °C.

Thermal Specifications
1. Ground / thermal vias are critical for the proper
performance of this device. Vias should use a .35mm
(#80 / .0135”) diameter drill and have a final plated thru
diameter of .25 mm (.010”).
2. Add as much copper as possible to inner and outer layers
near the part to ensure optimal thermal performance.
3. Mounting screws can be added near the part to fasten the
board to a heatsink. Ensure that the ground / thermal via
region contacts the heatsink.
4. Do not put solder mask on the backside of the PC board in
the region where the board contacts the heatsink.
5. RF trace width depends upon the PC board material and
construction.
6. Use 1 oz. Copper minimum.
7. All dimensions are in millimeters (inches). Angles are in
degrees.
