Hi, I'm looking for any information about possible topologies of 135° Hybrid Coupler (3dB) with in L-Band.

Thank you in advanced.

135 degree hybrid coupler

hi, riskio
i am familiar with quadrature, 180 degree coupler.
but i can not imagine about 135 degree hybrid coupler. (because of my poor knowledge, he he.)
can you give more hint to guess?

suspect

I suspect that this is a 90 degree coupler with one output line 45 degrees longer than the other before they get to the next stage (amplifiesr perhaps).

I just did a 90 degree Branch line coupler for L-Band1.75-1.85, design is
in /\DS 2002C and you can do as suggested above and add a 45degree
line to one side. 45degrees is ~475mil's long.


Hope this helps

i agree
use the straight foward branch line coupler design
and add a 45 degree line after to one of the legs
of course be aware of your effective wavelength so on
all ezily modeled
