    LTSPice filter

    Hello everybody, I am trying to simulate a line filter (Wurth Electronik) on LTSpice but I do not have the same result which is written in the datasheet for 50 ohm / 50 ohm sym. I joined my circuit, the datasheet and the .zip (including .lib and .asy) of the filter. Thank you for your time.

    SAW Filters Package Type

    Hello, I'm currently working on qualifying certain kinds of components, for that I need to know their type and category in order to know which tests are applicable. I have a SAW filter from Qorvo, PN: 885062, I've been judging this as a Hybrid Microcircuit because of the acoustic waves, but the...

    Volt/Amp dependent RLC band pass -> Loudspeaker expander using lightbulbs

    hey everyone, my name is max and I like to tinker with amps and speakers :) I want to create a input energy dependent frequency shunt network which goes in parallel with a loudspeaker, at low volumes a certain midrange frequency should be shunted off the loudspeaker, the shunt effect should go...

    How many filters do I need for a battery charger?

    Hello again, I have some concerns about how many EMI-filters that I should use for my AC/DC charger? My charger is operating as a low-power charing (950 W). I have read in in different articles, that some charger have only one input filter, and in some other cases they also have a output...

    EMI Filters for converters

    Do anyone how to draw typical EMI filters in LTspice? I have read in different articles on the internet, and it seems they differ in design time to time. I have attached my file so you can see how it looks like. I am suppose to have another filter my DC/DC converter as well.

    Phase Shift problem in audio equilizer

    Hello everyone, I am new to filter design and I want to design an audio equalizer. I used Sallen key topology design calculator from: http://www.changpuak.ch/electronics/Sallen_Key_Bandpass_light.php I designed five band bandpass filter having simple low pass and high pass for initial and final...

    Using an antenna analyzer as a network analyzer...

    I've searched the Web, but I can find no mention of using a common USB antenna analyzer (such as the Mini60/SARK-100 with software) to graph the band-pass of an HF filter. To me, it seems like a no-brainer, but perhaps I'm missing something critical here: Antenna analyzer-->LPF/HPF/BPF...
