Sven -- You can find the "Rat Race" (0/180) hybrid at 
http://www.microwaves101.com/encyclopedia/ratrace_couplers.cfm.

The Microwaves101 source has a description of the Quad-hybrid (they call 
it a branchline coupler) (0/90) at 
http://www.microwaves101.com/encyclopedia/Branchline_couplers.cfm. The 
quad hybrid can be seen in 23 & 13 cm PA's by N2UO 
(http://www.nd2x.net/n2uo-1.html) & DL4MUP 
(www.qsl.net/dl4mup/UKW45/UKW45_w.pdf).

You might want to bookmark the Microwaves101 web site  
(http://www.microwaves101.com/index.cfm) as a good "go to" web site for 
RF questions.

73, Tom
