DESCRIPTION
The BGY1816S is a three-stage UHF amplifier module in
a SOT501A package with a plastic cap. It consists of three
NPN silicon planar transistor dies mounted together with
matching and bias circuit components on a metallized
ceramic AlN substrate.

MOUNTING RECOMMENDATIONS
To ensure a good thermal contact and to prevent
mechanical stress when bolted down, the flatness of the
mounting base is designed to be typically better than
0.1 mm. The mounting area of the heatsink should be flat
and free from burrs and loose particles. The heatsink
should be rigid and not prone to bowing under thermal
cycling conditions. The thickness of a solid heatsink
should be not less than 5 mm to ensure a rigid assembly.
A thin, even layer of thermal compound should be applied
between the mounting base and the heatsink to achieve
the best possible thermal contact resistance. Excessive
use of thermal compound will result in an increase in
thermal resistance and possible bowing of the mounting
base; too little will also result in poor thermal conduction.
The module should be mounted to the heatsink using
3 mm bolts with flat washers. The bolts should first be
tightened to “finger tight” and then further tightened in
alternating steps to a maximum torque of 0.4 to 0.6 Nm.
Once mounted on the heatsink, the module leads can be
soldered to the printed-circuit board. A soldering iron may
be used up to a temperature of 250 °C for a maximum of
10 seconds at a distance of 2 mm from the plastic cap.
ESD precautions must be taken to protect the device from
electrostatic damage.
