But I can't find anything in my 03 Handbook on the subject. I understand the 'how,' but would like to know what available devices to use, and where to get small quantities. Thanks.

I'm not sure if you will be able to use PIN diodes at such a low 
frequency. The carrier lifetime may be too short.

It is not a subject I know well, so stand to be corrected.
