New for September 2020. Terminations are resistive components that are used to absorb a microwave signal. This is a pretty mundane topic, no one wants "she designed a new form of microwave termination" in their obituary. But it pays to understand the subject.

By the way, we added a category for "terminations" in the encyclopedia. Categories are lists of related pages. You can search the categories by going to the encycloppdeia page, and pulling down the menu at the top and set to "filter by categoy" (as opposed to the default "filter by topic". Competitors can use this feature to estimate the nunber of pages Microwaves101 has posted in the encyclopedia, nearing 1,000 at the close of year 2020. As Nikita Kruschev once said, "We will bury you!" (in Microwave knowledge).  Enjoy!

The three characteristics of terminations that must be considered are:

Characteristic impedance (usually 50 ohms, sometimes 75 ohms. and hundreds of ohms in a waveguide)

Bandwidth (including whether it must be DC grounded)

Power handling (often deterrmines what marterials are used)

Styles of terminations include:



Surface mount


On-chip (monolithic)

To start this discussion we posted a page on dot terminations, here.
