AH118

¼ Watt, High Linearity InGaP HBT Amplifier

AH118-89G 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.

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.

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

located on the website in the “Application

Notes” section.

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.
