The inevitable Smith Chart in pdf form. An excellent Smith Chart discussion at Spread Spectrum Scene.

Ode to a Smith Chart

O, circles, circles, round and round,
they’re coming out of my ears.
At Whence I do but hear that sound,
it enlights my darkest fears.
A constant rho, a constant z
and VSWR
They come into and fill my head
then leave like a speeding car.
One day perhaps I’ll understand,
the purpose of this dross
but until then the chart’s unmanned
and I feel like a toss.

Michael Barker, Elen302 2000.

Excellent S-Parameter Overview

Is at Spread Spectrum Scene, and another, dealing with amplifier design is from Agilent. Another here and another from from Anritsu.

Feedback, marks

Attached are the marks. Everyone did the lab and the average is around 80%. There where several 100% and only 1 person did really terribly with 27%, and that was because it was missing a large chunk of information and graphs.

Please check marks, 2016
