My RF app-note collection jumps from AN282 to > AN419. The Applications notes in my 1988 copy of "RF Data, Vol. II" also jump from AN-282 to AN-419, and my 1966 copy of "The Semiconductor Databook"--where app notes aren't yet even numbered--is too early. Maybe this info will help you zero in on which Motorola databook you need? Siliconix had an AN-72 "FETs in Balanced Mixers" (July 1983 FET design catalog) describing an active 2-FET 50-250MHz mixer using U310s that might be of modest interest -- I'm not sure what you hope to find. Fig. 5 in the article includes the following notation: "(from 'FET RF Mixer Design Technique', S.P. Kwok, WESCON Convention Record (1970) 8/1, p.2.)" I had my hands on (but passed up) Motorola's 1972 three-volume Semiconductor Data set this past weekend--wonder if that had it? Best luck, James Arthur

More bracketing: You reminded me that I have a 1973 Motorola Semiconductor Data Library book. No App Notes included, but at the end there is a list of abstracts of available App Notes. The list jumps from AN-408 to AN-411. Maybe AN-410 sucked? Or maybe had information Moto decided, quickly, was better not shared?

Thanks for the info, I have the 1969 issue of "The Semiconductor Databook" and it lists ANs 3 to 124 (With many left out) I also have the Siliconix ANs, they are useful, but I have heard (about 3rd-hand) that Motorola AN410 is full of good info. May have been in the 1972 set. It appears not to be in the 1973 set. Barry
