Subject: Re: [UKMicrowaves] 6cm tests
Why not replace the SPF5189 with one of these, which does seem to be spec-ed for 6GHz..https://www.mouser.co.uk/datasheet/2/472/SKY65017_70LF_200528I-1524673.pdf
Should be a straight swap??
Looking closer at specs, they seem biased towards 2Ghz. 6Ghz seems to be real limit so 5.7Ghz looks poor.
Guess one needs devices speced to 10Ghz then it should be fine at 6.
