The simulation is done for single device and  simulated results are as expected. 90  Degree hybrid also works fine. The problem arises when I use this hybrid for combining . The  output is 2.5 dB less them expected .has anyone  done simulation  for combining two PA using 90 deg hybrid or 2 way WPD.  Kindly help
