    ADS Simulation substrate issue

    Hi everyone, NOTE: I am using ADS almost for 6-7 months to design RF filters. I design filters and simulate them. From now on, I used 1 layer subtrates like in Fig1 for simulations. I have a circuit which includes both low pass and high pass filters. For this circuit, firstly, i used 1 layer...

    [SOLVED] Simulation and PCB are not even similar

    Is there any tool that I can measure the impedance on pcb that you can advice ? @barry

    [SOLVED] Simulation and PCB are not even similar

    Hi everyone, About 1 month ago, I have posted a thread on a similar topic. The topic title is "Basic LC High Pass filter simulation in ADS is not the same with real PCB". The PCB and ADS simulation does not match for cut off frequency. I still manage to do it with valuable comments. Now, I...

    [SOLVED] Basic LC High Pass filter simulation in ADS is not the same with real PCB

    Rf tools choose the right values for a specific cut off frequency, I do not. If capacitances are the main cause of these parasitic effect and cut off frequency shift, It means that i have to design a different circuit for the same cut off frequency. Do you know any other reliable tools to...

    [SOLVED] Basic LC High Pass filter simulation in ADS is not the same with real PCB

    Hi, I am new in RF electronics. I am learning ADS and other theoretical stuff about RF. I thought that i can create an Elliptic LC high pass filter on real PCB board to exercise. Before i create the board, firstly, i have chosen a high pass cut off frequency from RF-tools website. The specs...
