Product Description
Functional Diagram
The AH2 is a general purpose, high dynamic range
amplifier targeting cable TV markets. The combination of
gain flatness, high linearity and bandwidth make it ideal for
CATV distribution, cable modem and laser diode driver
applications. The AH2 is designed for 75 ohm systems and
can operate directly from a +5 Volt DC regulator. The
device is manufactured using reliable GaAs MESFET
technology and boasts an MTBF of >100 years at a
mounting temperature of +85 °C. It is available in the
environmentally-friendly lead-free/green/RoHS-compliant
SOT-89 package. All devices are 100% RF and DC tested.

AH2-G (Green / Lead-free SOT-89 Package) 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 AH2-G will be marked with an “AH2G”
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
an “AH2” designator followed by an
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.

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.
