I have to design a coupler. i did it as a coupled line coupler , however not getting the specs. Specs are

C = 20dB

Isolation > 30 dB and insertion_loss < 0.5 dB.

frequency band - 10- 12 GHz

With alumina substrate .

Can somebody hints how to achieve the same. Also guide for relevent literature for the coupler design .
