5 port  combiner transfer function ?
 
 5 port  combiner  , config 
 
2    ports      50  ohms      load
2    ports    power  input     50 ohm
1    port    power  out      50 ohm
 
Is  the  power  out  simply   i/p 1 + i/p2  =   o/p ??
 
or  do  the  p1 and p2   powers  need to  be closely  matched 
if  so  how  closely ??
 
Tnx -G
