Hello This is my first thread on this forum, I couldn't find another one that would answer my question so here we go: I want to design a loudness measurement device. I want to use it for measuring the level of street noise in a room. I figured probably a true rms to dc converter is what I need as the main piece of hardware, since I can not as
We got to about the stated efficiency and frequency on a family of 5V-1V buck ICs using RF CMOS SOI and using only Coilcraft kit inductors & caps we bought from Digi-Key, with no "de-embedding of passive losses" marketing trickery. Just "wallplug". So I think this can be done with superior switch devices. The RF CMOS was not very sensitive
Hello All, I'm try to make a RF-DC converter, which includes some diodes. When I'm trying to match the input side for a specific power in LSSP simulation, say for 5dBm, I'm getting the following graph, 134352 I can see a sudden jump for a very small frequency change. Is there any change to be made in the 'Solver' set
Many low-cost buck converters for applications not involving RF use hysteretic control. I'm sure their block diagrams (in some cases) would be enlightening. You may not (probably don't) want much deadband / hysteresis because that is going to make for more low frequency ripple voltage on the output. If you have a simple comparator you may end up a
Hi, i am designing RF ENERGY harvesting for IMD. for that i need RF-DC converter with input -0.1?w and output 1.5 v.if it is possible through charge pump(villard or dickson)
Below please find the link for building a microwave oven electric field detector using the RFD102A (RF-DC converter) module from RF Diagnostics, LLC along with a surface mount LED and a dipole antenna made from the wires of a 1/4 leaded resistor. It's a fun gizmo to show the electric field strength on the outside of a microwave window. The same de
Hi, I need to simulate the performance of Envelope Tracking DC-DC converter with PA as shown in figure below. The problem is envelope signal varies quite slowly(MHz) and RF input to the PA input is in GHz. This means that i have to run transient simulation for very long time but with very short time step. It will consume huge amount of time. I r
I've been studying VHF DC-DC converters to see how to make the most efficient and smallest size of an envelop tracking power supply for an RF transmitter power amplifer. It needs to be a capacitively coupled (or transformer coupled) boost converter so the output voltage can go down to near zero volts. I'm thinking of using a lower frequency like
i'm currently designing RF to DC converter that doesnt require external power supply.. i already have an rectifier design together with its out.. the thing is i need a differential circuit that combines and amplify the negative and positive rectified signals into a single rectified signal without any external powersupply (Vdd) it should only hav
I have a diode multiplier circuit and I need to somehow take DC out of the 1w RF signal. Is that possible? how?
I need some help on designing a RF choke. A have a PCB that is supplied with 9-32 Volts where it gets regulated to 15 Volt. The pcb has a homemade-non manufacturing rf choke and some other signal conditioning components just prior to the 15 V DC/DC converter. The DC/DC converter couldn't fit in the screenshot but its just right of the 10K resist
hi all....i'am study about RF to DC converter..i need some advice how to design RF to DC converter..i also asking any example of RF-DC circuit that will produce 5v of DC output.. thanks
Hi good day everyone! Can anyone help me simulate the RF to DC converter circuit that I have created in Agilent ADS? I want to know the output voltage given an input frequency (915 Mhz) and also the correct specs like the width and length for my microstrip design? THank you
I am doing a project that converts rf power to dc power. Currently i am looking at the possible simulation software to study various voltage doubler designs and is pondering whether pspice or ads should be a more appriopate software for use.
ADS. You can use WLAN examples to construct your own RFID test bench.
GaAs is the most suitable for a linear and efficient RF power amplifier. But in the same time is the most expensive process. Most of the WCDMA PA?s on the market still use a standard linear amplification, and sometimes using adaptive bias or a DC/DC converter on Vcc to improuve the efficiency at low power.
Hi! everybody I'm simulating a 4th harmonic mixer with an anti-parallel diode pair, LO=8.5GHz;RF=34-36GHz;IF=DC-2GHz. When i simulate it as down-converter,the conversion loss is about 8 to 10dB,but when use it as up-converter,the conversion loss changes to 2 to 4dB. but i think the conversion loss should be the same whether use it as up
need to design rf power amplified for Dc:dc converter. suggest good ref
I need paper or schematic about RF to DC converter. if you have, please upload . Thanks in advance
