ATR offer a wide selection of SMT chip terminations handling input power
levels up to 250W and covering frequency ranges up to 4 GHz.
the surface mount termination is improved by increasing the solderable
grounding area. This eliminates the need for bolt down heat sinks and
tabs, thereby reducing assembly costs.

Suggested mounting procedures:
1.Solder part or leads in place with controlled temperature iron (260℃).
2.Drill thermal vias through PCB and fill with solder.
