    Need help in optimizing RF antenna balun on two port network analyzer

    The schematic I posted here is just to show as a sample. Not exactly looks like that in actual circuit. Yes, it has differential outputs at 2 and 3.

    Need help in optimizing RF antenna balun on two port network analyzer

    Yes, that's not the real schematic. Phase difference is 180 degree in ADS simulation. I haven't tested it on the board and network analyzer yet.

    Need help in optimizing RF antenna balun on two port network analyzer

    S21 and S31 are the insertion loss. 1. Phase difference requirement is 180 degree between 2 arms. Magnitude difference requirement is 0 dB between 2 arms. 2. No 3. 50 ohm on each number 1, 2 and 3 (refer to the schematic)

    Need help in optimizing RF antenna balun on two port network analyzer

    What is the best way to optimize lumped-element RF antenna balun two port network analyzer? S21 and S31 have to be -3 dB. I have a circuitry that looks more or less like this one. Current Attempt #1: Port 1 of NA connected to Number 1 in the schematic above. Port 2 of NA connected to Number 2...

    Tri-band Antenna Impedance Matching Network Help

    What happen if the resonance (the 3 bands mentioned above) of the antenna (before matching) are completely off from where they are suppose to be? There is only one input to the antenna.

    Tri-band Antenna Impedance Matching Network Help

    Hi, I would like to impedance match a tri-band antenna using lumped elements. Target band: Band 1: 0.699 GHz - 0.960GHz Band 2: 1.71GHz - 1.99GHz Band 3: 2.11GHz - 2.17GHz How feasible is this if the network of L, T, pi and/or combination of L T pi is used? If this is feasible, what are the...

    Simulating a simple envelope detector circuit

    Hi, This is the expected output waveform. I am expecting output waveform with its negative side removed. The waveform should charge and discharge according to the RC values. Thanks

    Simulating a simple envelope detector circuit

    Hi, I am trying to simulate a simple envelope detector circuit on TINA simulation software. Here is the schematic: I supplied sine wave of 2.45 GHz and 1V amplitude. I am not getting the output waveform as expected. Any idea what might be the issue here? Thanks

    Need help in ADC Simulation with TINA

    Hi, This graph was generated using ADS8681 EVM board with our front end circuitry (physical board) connected to the board and captured by the ADC GUI software. I started off by downloading ADS8681 TINA-TI Ref Design on https://www.ti.com/product/ADS8681#product-details I constructed the...

    [ARM] Microcontroller Simulator

    Hi, Is Proteus still the best advanced microcontroller simulator to date? I would like to run simulations on an ARM-based MCU specifically by TI. If not, what is your suggestion/recommendation to simulate ARM-based MCUs? Thanks
