EMRFD is out of date in the sense that many of the designs can no
longer be built straight out of the book unless you're willing to
scrounge for NOS components. But it's EXPERIMENTAL design, so
substituting newer parts is very much in the spirit of the book.

EMRFD is an excellent publication but the edition I use ( First Edition, 2nd printing ) has so many errors I have to check the corrections book before I trust anything just to see if an amendment has been made. The colour of the appendix CD is difficult to distinguish, why not have two colours that are opposite each other in the spectrum?
Buy it, read it, read it again.

John VA7JBE,
For all pass circuits look at EMRFD there is a couple of chapters and you can use the designs described.
EMRFD Experimental Methods for RF Design. Do not let the claim of old or outdated dissuade you
as knowledge does not decay.
