There will greater intermod both receive and transmit with the 1N4007
over the true PIN diode, and more than that with the 1N4148.
I know I've seen an article on the topic, probably in VHF
Communications. Found it in the index:
1994/1 "Intermodulation Properties of Switching Diodes" by Dr Ing Jochen
Jirmann, DB1NV, pages 12 - 18. Last year that article was probably
available on-line, today I think it isn't but the publisher will sell
back issues.
It might be at:
http://homepages.ihug.co.nz/~jaking/TS-940_02.htm#_Toc155846465, or
might not. Yup there are scans of the article, it will load slowly
at the end of a long web page.
