Hi all,

I'm looking for a low power handling and low price 90 degree hybrid coupler part which covers 200 MHz to 850 MHz. Anybody has a solution?

Best Regards,
Hadi
 

The Bandwidth is more than 2 Octaves at Low Frequencies, it's pretty difficult to find it within specifications.
It's easy to find a Hybrid Coupler at High Frequencies with a bandwidth more than 2 Octaves.
However you can ask to Anaren Microwave, they may have a solution.
 


Thanks, I have found C0409J5003AHF from Anaren, the price is exellent, the only thing I'm not sure is how is the Amplitude balance performance between 200 to 400 and whether it exceeds 4 dB or not!

It will probably exceed.Therefore I'm saying it's more difficult to find Low Frequency Passive Components rather than High Frequency ones.
In fact the Bandwidth can be extended by using "multi-section" coupler but Amplitude and Phase Balance can unfortunately no be maintained simultaneously.
