I'm looking for a Schottky diode to use for the rectifier now.
I intend to design a rectifier with maximum efficiency when the input power exceeds 30 dBm(31, 32, 33...dBm).
What diode should be used in this case?
If you know the name of the diode I want, please let me know.
What should be...
Thanks for your kind reply.
I finally did rectifier EMsimulation well and my rectifier has more than 60% efficiency.
The range above 50% efficiency is approximately 500 MHz.
Thanks again. I think the problem was solved.
And also I'll refer to the Youtube link for doing tutorial.
Thank you for reply.
I mean, I wonder if the accuracy can be improved by drawing a Pad on a layout with a capacitor and a resistor and simulating it.
As you know in my layout, I only drawn the pin for connecting C,R,Diode in circuit.
I didn't drawn the Pad in layout because they doesn't...
I changed the frequency range from 0 to 4GHz.
That's a surprising result. I just changed the frequency range, but the efficiency went back up to 64 percent!!
Could you please the reason?
In the case of rectifiers, I know that the goal is to obtain DC, but in the result window, it seems that...
Dear volker,
When I checked efficiency of rectifier in 2D circuit, the efficiency is about 75%..
But when I import the EM data with symbol to circuit, the efficiency is about 25%...
What is wrong..?
I did this simulation about 1 month.. but I don't know what the problem is.
At first, I...
Thank you so much.
I modified as you advice, and then I checked the result.
But there is a strange thing. The efficiency is very defferent depending on where Vout net and R.
The first image's efficiency is about 100~120%.
And second image's efficiency is about 20~30%.
The equotion to calculate...
Thanks again, :)
But I'm confusing how to set the Port calibration and +,- terminal...
You said that "When using EM results in schematic, grouping of pins to ports is not required here. The wiring of EMmodel at schematic level is sufficient, there is no need to group the pins into one port with...
Hi. I am a beginner at ADS Momentum.
I have designed the rectifier using HSMS285C schottky diode.
I also designed layout the rectifier only using TL, but I don't know how to connect the Lumped elements and Diode in ADS circuit and how to setup the port.
My simulation step is like :
1. Sketch...
Thanks for your reply.
I mean that port1 be located at the start of PCB board like attached image yesterday.
If I make the PCB board to measure, the Port1 must be located at the end because the antenna will be connected to Port1.
But when I open the 3D EM Preview, the Port1 is not at the end of...
Thanks for your reply.
I extend the result of frequencies upto 10GHz, there are another resonance points.
So i think that's why the efficiency was too low at 2.45Ghz.
But I have a one more question about Layout tool in ADS.
I want to place the Port1 at the start of substrate to connect HW...
Thanks for your reply.
As I said above, the Layout was modified for matching 2.45GHz.
I designed layout, made the symbol, did the simulation only Microstirp lines without any components like Diode, Capacitors, Resistor.
And then I made the wires to connect the C,R,Diode to ML after importing...
Thanks for your reply.
I modified the layout to match 2.45GHz.
I understand how to connect the Via in lay.
But even though it is well matched, the rectifier's efficiency is too low.
Is there anything wrong with the wire connection after importing the EM model into the circuit? Or is there...
I'm using ADS to check the efficiency of voltage doubler, but there are something problems.
I designed the rectifier like below image and i did simulation in EM simulation that ADS support.
In the 2D circuit, the efficiency of rectifier is about 60%.
However when I did simulation using Layout...
