Could anyone teach me that how to calculate trace width and thickness
in a short time (µ second) with 7KA current . this problem confuce me
Hope anyone can help me to solve it .

I want to creat S2P into simulate software(MWO) but i don't know ,how to measure L ?
If i use VNA (vector networe analyse) to measure inductor ( L ),what type
(MA or DB), can be used. and how to do this test ?
HOPE anyone can tell me !
thanks a lot!
Does anyone have this experience with is .and i want to know,as below
(1) Increase orders in passive Low pass filter whether it can reduce the harmonic
(2) i use NPO cap. and hight Q inductor whether it can reduce the harmonic
(3)if i design LPF and HPF on one board,what is importance...
Power spectrum unit ?
I want to input a -60dBm/Hz power in 4MHz ,but our signal generater can only
input dBm signal ,if i press -60dBm on signal generater, I don't know that is right?
and what is different between dBm/Hz and dBm .
Can anyone tell me !
thank a lot
i need to input signal level of -60dBm/Hz (+20dBm average and +35dBm Peak,at
3.175MHz~5.2MHz) to my sample ,pls tell me what shall i do ?
And what is the different between dBm/Hz ,dbm ,why sometime use dBm/Hz and
sometime use dbm on any book ?
Creat S2P file in MWO ?
but ,if i use ideal model that is not accurate between
real and simulate circuit ,so i must to creat s2p ,but
i find ,that is not accurate. so i think ,maybe what is wrong in my way!
Creat S2P file in MWO ?
(1)i creat a passive circuit then use this circuit's S2P file to become a input port and output port.(input port and output port is the same)
(2)Then use this input(passive circuit) and output port(passive circuit) to simulate my 4th filter.
pls. tell me how...
Very thanks a lot!
Attached file is my circuit. file complex port is a complex impedance R+(R//C)==>
270+(750//150nF),and i created a new circuit (complex port) than used portin module to my circuit, but S21 and S11 is not accurate,so i don't know what is the best way to solved my problem ...
thank a lot! but this complex impedance are include 3 inductor and 2 captance,shall i transfer this equal
impedance ,first ? then use the way that you offer
I ever use one way, that is creat a new circuit,then use portin module and this portin's impedance is a
complex value, but it is not...
