The AG402-86 consists of Darlington pair amplifiers using
the high reliability InGaP/GaAs HBT process technology
and only requires DC-blocking capacitors, a bias resistor,
and an inductive RF choke for operation.
The broadband MMIC amplifier can be directly applied to
various current and next generation wireless technologies
such as GPRS, GSM, CDMA, and W-CDMA. In addition,
the AG402-86 will work for other various applications
within the DC to 6 GHz frequency range such as CATV
and fixed wireless.

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.
