Straight Talk About Directivity
Directivity plays a critical role in determining the accuracy of your RF power, VSWR and return loss measurements. Errors due to directivity can be significant and may influence the decisions you make based upon your test results. The purpose of this article is to explore the subject of directivity and to set appropriate expectations.

RF Power Measurements in the Field
There are many valid reasons to make RF power measurements in a field environment. It may be difficult to actually select the top reasons but I feel reasonably comfortable in selecting some important reasons to make a field power measurement.

Thermal Design for conduction cooled loads
What parameters do I need to know before using a conductive load? Important considerations are ambient temperature, and how much free air-flow is available.
One would also need to know the amount of heat needed to dissipate, i.e. A transmitter with a 100 watt output would require...
