Waveguide power divider?

Hi,

I would like to do waveguide power divider 3dB/3dB, but i do not know, how can I to do it wideband.

I have rectangular waveguide R120 (WR75), freq. cca 10 GHz - 15.5 GHz.

Can you help me?

Thank!

You can try a hybrid waveguide coupler. MDL company makes molded hybrids with calibrated parameters that can be brazed in standard waveguides. The specified bandwidth, however, is ~ 1 GHz wide. You can use it over a wider bandwidth with a poorer isolation and insertion loss.
Or you can try to make or buy a magic tee, this is available for the full waveguide band.

Thank,
the magic tee have not good S11, there is problem with matched. :(
