    Very low RF-DC conversion efficiency in ADS (SMS7630 & HSMS-282E)

    Simulating RF rectifier in ADS (2.45 GHz, 5 dBm). Using HSMS-282E gives 11% PCE, SMS7630 gives 21% PCE. Matching is correct (good S11). Using SPICE models from datasheets. Load = 2 kΩ. Using HB with proper Pin/Pdc equations. Why is PCE so low? What am I doing wrong, or are these values...

    how to calculate the capacitance of of cross-coupled voltage doubler

    Hi everyone, as you see on the circuit, I would like to calculate the Cout and C1 and C2 for a given Vout and Iout. my first simple trial is that: Q=Cout*Vout Iout=Q*Freq --> Q=Iout/Freq=Cout*Vout --> Cout=Iout/(Vout*Freq) alos I took C1=C2=Cout I tried this on simple voltage doubler made by...

    Computing the efficiency in LTspice

    Hi, I’d like to compute the efficiency of attached circuit for V2 range 20-300V. Can you please check if the formulas are correct? Results:

    Can you give me some hint for my PSPICE project?(transformer, diode)

    The project is about designing a transformer that converts 22V AC to 1V AC and connect it to voltage doubler as V_in So here's my schematic and simulation result. I'm having trouble with analyzing the result. The D1N914 diode that is recommended for this project, had Vd,on of about 930mV when...
