AH420
4W High Linearity InGaP HBT Amplifier
Mechanical Information
This package is lead-free/green/RoHS-compliant. The plating material on the backside metallization is Matte Tin. It is compatible with both
lead-free (maximum 260
°C
reflow temperature) and lead (maximum 245
°C
reflow temperature) soldering processes.
Outline Drawing
Product Marking
The AH420 will be marked with an “AH420G”
designator with a lot code marked below the
part designator. The “Y” represents the last
digit of the year the part was manufactured, the
“XXX” is an auto-generated number, and “Z”
refers to a wafer number in a lot batch.

Functional Pin Layout
Notes:
1. A heatsink underneath the area of the PCB for the mounted device is recommended for proper thermal
operation. Damage to the device can occur without the use of one.
2. 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”).
3. Add as much copper as possible to inner and outer layers near the part to ensure optimal thermal
performance.
4. 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.
5. Do not put solder mask on the backside of the PC board in the region where the board contacts the heatsink.
6. RF trace width depends upon the PC board material and construction.
7. Use 1 oz. Copper minimum.
8. All dimensions are in millimeters
