APPLICATION NOTE • APN1001: CIRCUIT MODELS FOR PLASTIC PACKAGED MICROWAVE DIODES
Conclusion
As a result of this effort, accurate and concise microwave models
are now available for commonly used, low-cost, surface mount,
SOT-23 and SOD-323 packaged diodes. The measurement
methodology utilized de-imbedding techniques valid at frequen-
cies through 10 GHz. This material will assist design engineers
to design and predict circuit performance using these popular
devices.
In addition, it was demonstrated that the inductance of the
SOT-23 may be significantly reduced by modifying both the
internal package wiring and the microstrip transmission line.
This further improves the frequency response of the package.
