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)
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...
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.
The antenna has been designed and fabricated.
Here are the impedance on each band.
Band 1: 0.699 GHz - 0.960GHz, Impedance: 11.756 - j135.919
Band 2: 1.71GHz - 1.99GHz, Impedance: 231.817 + j229.845
Band 3: 2.11GHz - 2.17GHz , Impedance: 63.544 - j186.479
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...
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
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
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...
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
