You might want to look into the ADL5511. It's a high dynamic range envelope detector and RMS converter designed for RF applications, but its datasheet suggests it can be used at low frequencies down to DC.
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
If you apply your RF to a tuned circuit at a low impedance point (capacitive tap or tap on inductor) then you can get a transformer action and have more voltage across the tuned circuit then applied at the input. But the power is still the same. You will need the minimum of .4V RMS of RF to get a diode to conduct and produce DC. Frank
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
i'm prefer to use uwb... thank..hopefully it will help me.. You mean on ultra wideband technology ? Are you trying to make some RF power harvesting ?
I am using a MCU and a GSM module in my project. MCU consumes 250mA (max), GSM module consumes 400mA(average) and while transmitting RF signals consume 2A (peak). And also MCU consumes 1mA, GSM module consumes 1,5mA while IDLE mode. I have searched for ultra low quiescent current DC-DC converters, find some possible ICs that is useful for me.
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 If you have the circuit, run a Transient a

Harmonic balance is going to be allot faster than SPICE for this type of problem assuming it converges OK. In addition you will want to play around with the driving source impedance so that's easier to do in an RF simulator. If you want to simulate a DC-DC converter then you will need SPICE.
Hi all, I am working on RFID system design. currently, I am working on the RF-to-DC converter part. I use cadence for this design but I have a hard time to simulate my system is pretty hard to generate the OOK waveform I want. takes a long time to run the whole simulation. Therefore, I would like to k
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
Hi guys, Do you have good companies to suggest me for doing such a RF mixed signal internship.?? THank you very much , it is very important for me. regards, Tahar
