Looking for COTS Phaseshifters

Dear all,

Im looking for some commercial off the shelf (COTS) phase shifters. It should be modularized, with very wide bandwidth. So far, i can only find phase shifters with less than an octave bandwidth... any ideas? It can be switched or analog, but it should at least cover the major phases such as 90, 180...

Hopefully, i do not have to design them on my own...


Thanks for the inputs!

in which frequency?
check narda or hittite or aeroflex

Unfortunately, these options are mechanical and narrow band. I am looking for one with phase shifts of more than an octave bandwidth.
I wonder if this is a possible option: http://beamforminc.weebly.com/

Has anyone tried them before?
