Title: Recommendation of good directional coupler Post by pancho_hideboo on Dec 1st, 2007, 4:11am Hi. When I do load-pull measurement, I use 4port_directional_coupler + variable_attenuator + sliding_short. This is well-known passive load-pull method. But my directional coupler is not good. Is there any good directional coupler of 5GHz ~ 6.5GHz ? The following system is very expensive. http://www.maurymw.com/products/rfdcs/loadpull/atsprods/atsintro.htm How do you do load-pull measurement inexpensively for 5GHz ~ 6.5GHz ? |
Title: Re: Recommendation of good directional coupler Post by didac on Dec 1st, 2007, 7:19am Hi, Have you taken a look at M/A-COM?http://www.macom.com/psc/jsp/ListParts.jsp?dataFile=couplers.txt, I used in the past Gunn diodes from them(not directional couplers) but I think they are pretty good at MW, if not maybe ANAREN(but I don't know it they reach your desired range of frequencies). Hope it helps, |
