Return Loss Bridge

 

开云体育

Is anyone on this group have a return loss bridge for sale or know where a unit with HP type specs can be obtained at a reasonable price?

I want to use it for sat-com stuff so the top end frequency does not have to be above 500MHz but it would be nice to match it to my spec an (Agilent E4401B) up to 1.5GHz.

Thanks

Dave
 

I have several of those cheap ones on ebay and the good ones work perfectly fine up to 1GHz or even more honestly.
there is one made by a Russian seller which I find it the best. it also comes with metal casing and looks very professional
claims 3GHz but it's really good to 1-1.5GHz unless you can accept lower directivities when yeah 3GHz is not horribly bad?

also there is? mini circuit zfdc-20-4 (cheap on ebay) that works fine up to 1GHz
i think it has a 75 ohm version too

i do have a HP 86205A up to 6GHz which is dear to me ;-)?

I am never sure of the "real" performance when buying off ebay but if you have had success with them I will go and see if I can hunt them down.

Hi Dave,

I bought a Masters Communications RLB1500 from Amtronix, to use with my HP8935 you can see it here...

cheers Tim
