Hello,
I found the way to calculte this type of impedance with ADS of keysight. They have a calcultor called impedance line controller.
Thanks for your help

Hello,
I am looking for a document which allows me to calculate the impedances of multi-section Wilkinson dividers. I had an old document at the time but I lost it and despite my searches on the internet, I couldn't find it. it allowed to have the values of more than 7 sections. Thank you for...
hello !
i wanted to know how i can calculate the impedance on a microstrip line as below.
it's consist of a ground plane , an air dielectric above the Gnd, a substrate with its Er above the air substrate and finally the line.
i can't find the formula for it .
thanks
hello,
in my example I have a microstrip transition to a coplanar line. I removed everything that is components and on the line and I attack an RF amplifier. when designing my antenna network, I am well adapted but near my amplifier I would like to know how the adaptations are made if ever we...
Hello,
i wanted to know how is the best way to match a patch antenna array at high frequency like 24Ghz?
i know at this frequency lumped component don't work.
this would therefore mean that the S parameter file was measured directly on the pins of the component and in the datasheet we have the S parameter measurements with a matching circuit according to the frequencies used? is it correct?
what is confusing for me is how to interpret these two curves...
I am self-taught in the field and I don't know everything. can you explain to me very simply how to understand this and how to interpret it on the datasheet please
hello, I have a little problem understanding the datasheet for this component.they talk about small signal gain equal to 24dB @900mhz while on the S parameter file provided, the gain is 13dB. why this difference?

I simulated a bandpass filter between 1.5-1.6 GHz @3dB with the ADS keysight passive circuit guide design. I used a coupled line filter with FR4 as substrate.
during the S21 simulation, I have frequency rises at frequencies 2Fc, 3Fc etc, a bit like harmonics of a fundamental. What is this due...
hello,
I would like to build a sectoral antenna using 5 yaggi antennas, I would like to know how and which components to use to connect the antennas to have the direction of arrival of a signal.
in other words, how is such a chain constituted? I can't find any paper on the subject.
thank you
thanks @volker@muehlhaus for your soulution.
it's exactly the phase difference and want to meausre .
@FvM i built a four ways beamformer and i wanted to measure the phase difference.
Now i want to know if and why i can measure the phases contibution beetween the outputs without plugin...
hello,
I want to know if it's possible to measure the phase beetween two signals with à network analyser.
the test i want to realise it two put a signal throught a combiner and measure the phase with a network analyser.
thanks
