    HFSS Stripline Simulation: with a splitted ref plane

    hfss 11 stripline Hi all, I'm a freshman in HFSS and also in electromagnetic simulation concept. So, I'm not so sure about whether i'm correctly simulating or not. Here is my problem: I have a stripline structure with a splitted upper reference plane. I want to simulate in HFSS this structure...

    The condition for start up of oscillation

    It's another way of saying stability factor for that specific circuit is smaller than 1 k<1 This means reflection coefficient is greater than 1, where the circuit presents a negative input resistance. The wave reflected off a positive resistance load would be smaller than the incident wave...

    Output problem in ADS

    Dear Friend from component palette select simulation-DC then select DC and add it to your schematic by this way in the simulation results you can see your dc node voltages good luck

    Explanation of LoadPull in RF power amplifier

    Re: LoadPull hi again, In the schematic, there is a load tuner placed at output. During the simulation its impedance will be automatically changed. There is no need for you to thing of it. Results of the simulation will give you load pull contours, on which the output power level is same. You...

    Explanation of LoadPull in RF power amplifier

    Re: LoadPull Hi dicket, The idea behind the load pull is shortly; If you use small signal conjugate matching, you assume gain vs. power characteristic is linear. However, since the amplifier is dealing with higher input power levels linearity of the amplifier beraks down in the limits. So, you...
