Re: HYBRID QUADRATURE JH-6-4 or equivalent
|
Hi All,
As I thought, T1 material was #75.
replaced it with BN-43-2402 (7 turns tapped at 5 from GND)
then the high band loss was resolved.
?
about the 2MHz disturbance.
conclusion was a error or noise of NanoVNA (F_V2).?
so broken H4 was temporarily repaired and replaced.
?
The plots are similar to those of Mark.
Isolation between port 0-90 is also sufficient.
?
I made a slightly smaller Hybrid with the same circuit and values.
and tried to oppose it as Splitter - Combiner.
The result seems to be good.
?
I added some pictures to my blog.
?
The coil and choke are still to be checked.
?
By the way, do I have to make a new album to upload to this forum?
?
tnx & 73, Hisami 7L4IOU
