 Hi ALL,

 I want to combine two CGHV59350  GaN devices in ADS  using 90 Degree Hybrid at 5.6 GHz. 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
