Assembly Guidelines

Assembly Diagram

The backside of the CMD177 is RF ground. Die attach should be accomplished with electrically and

thermally conductive epoxy only. Eutectic attach is not recommended. Standard assembly procedures

should be followed for high frequency devices. The top surface of the semiconductor should be made

planar to the adjacent RF transmission lines.

RF connections should be made as short as possible to reduce the inductive effect of the bond wire. Use

of a 0.8 mil thermosonic wedge bonding is highly recommended as the loop height will be minimized.

The semiconductor is 100 um thick and should be handled by the sides of the die or with a custom collet.

Do not make contact directly with the die surface as this will damage the monolithic circuitry. Handle

with care.

GaAs MMIC devices are susceptible to damage from Electrostatic Discharge. Proper precautions

should be observed during handling, assembly and test.
