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.

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

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 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.

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.

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
