Product Information
¼ Watt, High Linearity InGaP HBT Amplifier
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.

Product Marking
The component will be marked with an
“AH118G” designator with an alphanumeric
lot code on the top surface of the package.
The obsolete tin-lead package is marked with
an “AH118” or “E099” designator followed
by an alphanumeric lot code.
Tape and reel specifications for this part are

Mounting Config. Notes
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.

Notes:
1. The amplifier can be operated at 105
°C
case temperature for up to 1000
hours over its lifetime without degradation in performance and will not
degrade device operation at the recommended maximum 85
°C
case
temperature for the rest of its lifetime.
2. The thermal resistance is referenced from the junction-to-case at a case
temperature of 85
°C.
3. This corresponds to the typical biasing condition of +5V, 160 mA at an
85°C case temperature. A minimum MTTF of 1 million hours is achieved
for junction temperatures below 247
°C.
