The Sharp End of RF Power Measurement


Hi Chuck,

Little do you realize


Very little, it appears.

(or you are especially diabolical to have
introduced it), but within this monograph offered is the heresy of the
Source mismatching the load (the heresy being that any source of
sufficient power does not embody the nominal 50 Ohms Impedance).

It even contains the classic math introduced by Stephen F. Adam back
in the mid 60s for the National Bureau of Standards - and later
published by Hewlett Packard (both notorious hotbeds of technical
corruption in the matters of source impedance).

Thanks.

73,

Chuck
