    Looking for a VHF/UHF 90 degrees Hybrid Coupler part

    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.

    www.werlatone.com

    They have wideband hybrids but I think they are expensive ..
