Does Matching Matter? (Diode Matching for Diode Ring Mixers) -- Nick M0NTV Finds the Answer (Video)


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.
