A Primer on PIN diodes

Bob, G3OOU posted an interesting link to the GQRP list a few days ago - a primer on PIN diodes. This was produced by Microsem,i who puchased Unitrode. Unitrode are firm that was very famous for the manufacturer of PIN diodes and who produced a classic reference book on the subject.

If anyone is interested in experimenting with PIN diodes, you can use some types or ordinary power rectifier such as an 1N4007 in PIN diode mode. There is an instructive thread here on the subject which points to an ARRL article by W7ZOI which uses a 1N4007 as an attenuator in the IF amplifier of his spectrum analyser (see fig 5).
