In this video, Nick M0NTV takes on a hot topic in ham radio homebrewing: The matching of diodes in diode ring mixers. How should the matching be done and -- more controversially -- is this matching necessary?
I won't spoil it for you by giving the answer. Watch Nick's video to find out if it matters. (But a hint appears below.)
I think it is great that Nick has taken the trouble to look carefully at this issue, and has found info that will be of great use to homebrewers. And I really liked Nick's response to the fellow who suggested just going out and buying a commercial diode ring: Nick replied that he homebrews because he likes to, and because he wants to know how these circuits work. FB Nick.
I was also pleased that Nick gave some much warranted recognition to Pete Juliano for his idea regarding the placement of a trim pot on a diode ring. This idea made it into the Experimental Methods in RF Design book (under Pete's old call: W6JFR). Page 6.56.
