Hello,
I am using a synthesizer in my project. but I observed the problem that instead of showing carrier output it shows waveform-like modulation in the output.
Please guide as soon as possible.
Hello,
It is possible to use OPAMP as a single supply and get negative output from it.
In my circuit I am giving a 7-15V supply and want to negative output.
Please guide.
Thanks
Hi,
we have given ladder output to inverting pin of OPAMP so it convert postive to negative.
Thanks

hi,
Sorry updated the wrong block diagram.
Please find attached the updated block diagram.
Thanks
Hello,
Please find herewith attached an Image of a block diagram.
In this now we are facing that we get output voltage which is range from -2.8 to -0.6 V for (111 to 001 combinations).
But in our application, we want -5V as output. so is there any option to get -5V as output? The controller...
Hello,
I am designing an RF PCB. I have some queries regarding PCB designing/.
how to calculate the width of the trace(Transmission line). I have used one online calculator but in that calculated trace width is bigger than PAD of IC. so in that case what I have to do.
Please guide as soon as...
Hello,
I am using LT3840 DC DC converter in my project. but i have one problem that i have used same MOSFET M1 (BSC160N10NS3)and M2 (BSC160N10NS3) in my circuit.
But i have observed shorting in my PCB. Is it possible because of using same MOSFET M1 as in datasheet application note they have...
Hello,
I am using two FPGA in my two different project. one FPGA is XC7Z2035 -676I and second is XC7Z045-900I.
i have found that pin compatibility of both FPGA is same.
So can i use XC7z045 -900? is there any change in configuration. my idea is to check Decoupling, JTAG all the configuration...
Hi,
I am facing the error in ADS EM simulation, i got error of port mapping. Shows the error "port 1 does not have explicit reference pin."
also want suggestion regrading two layer substrate stack up.
Please guide me.
Thank you
Dear sir,
Thank you so much for your prompt reply.
My doubt regrading transmission line impedance clear with your prompt reply.
Can you please help me regarding length,when i have to calculate this.
Thank u so much.
Hello,
I am doing my first RF project. i want the help regrading trace width calculations. I have to design 6 Layer PCB in FR 4 material which my first layer contains RF signals.
My layer stack up is like Signal, GND , Inner layer, Power , GND, Bottom.
I have query regarding the RF PCB...
Thank you so much for your Prompt reply.
I need help that if i want to calculate 501 ohm-transmission line for 6 Layer where this layer matter. where i have to use layer stack up or copper thickness.
Please guide me.
Thanks you
Thank you so much for your reply. but still confused for which i calculate.
i want to calculate for 6 - layer ,50 ohms, FR4 1.6mm thickness.
Please guide me.
Thanks & Regards,
Nidhi Jani
Hello Everyone,
I am doing a project which have RF components in this. So i want to know that how to calculate 50 ohm transmission line trace width. This is my first RF project so need guidance about that. please help me regarding this.
I have to calculate the Transmission line Trace width for...
Hello,
I am using the custom board/PCB with ATSAME54P20A microcontroller embedded into it. Suddenly, I am getting "Unexpected chip identifier" error which I can't find solution to. Can anyone please help me how to solve this error.
I am using ATMEL ICE debugger with default clock setting of...
