    combining of two Power amplifiers in ADS

    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...

    reduction of insertion loss

    vr designing Wilkinson power divider am getting proper insertion and isolation loss for the basic ckt(i.e when i have used transmission lines).. but for the main ckt i.e when using microstrip lines am getting more power loss for 4way,12way divider. so can u tel me how it can b reduced.
