    RF Unit Converter Introduction

    This tool is a unit converter for voltage and power. There is an input for impedance that allows the relationship between power and voltage.

    Ohm

    The unit for resistance or impedance. Resistance can define the relationship between voltage and current and voltage and power. Based upon ohms law the voltage and current relatinship is:


    r = \frac{v}{i}

    and power is


    power = \frac{v^{2}}{r}

    Vpeak ?¢???? Peak Voltage

    Peak voltage of an AC signal is the peak amplitude.

    Vrms ?¢???? RMS Voltage

    The Root Mean Square Voltage or Vrms is:


    V_{rms}=\frac{V_{peak}}{\sqrt{2}}

    uV ?¢???? Microvolt (RMS)

    This value is the RMS voltage in microvolts.


    \mu V=\frac{V_{peak}}{\sqrt{2}}\cdot 10^{-6}

    uV EMF

    This value is microvolt with no termination or load.


    \mu V_{emf}=\frac{2\cdot V_{peak}}{\sqrt{2}}\cdot 10^{-6}

    uV PD

    This value is microvolt with with a load. When a signal has a matched load then half of the voltage is droped across the load. This value is the same value as uV, The unit is just explicitly defined as having the load.


    \mu V_{pd}=\frac{V_{peak}}{\sqrt{2}}\cdot 10^{-6}

    dBuV ?¢???? dB Microvolts RMS

    This unit is the decible of RMS microvolt.


    dB\mu V=20\log \left ( \mu V \right )

    dBuV EMF ?¢???? dB Microvolts EMF

    This unit is the decible of EMF microvolt.


    dB\mu V_{emf}=20\log \left ( \mu V_{emf} \right )

    dBuV PD ?¢???? dB Microvolts PD

    This unit is the decible of EMF microvolt.


    dB\mu V_{pd}=20\log \left ( \mu V_{pd} \right )

    W ?¢???? Watts

    Watts is a unit of power.


    W=\frac{V_{rms}^{2}}{Z_{o}}

    mW ?¢???? Miliwatts

    One thousandth of a watt.


    mW=\frac{W}{10^{3}}

    uW ?¢???? Microwatts

    One millionth of a watt.


    \mu W=\frac{W}{10^{6}}

    dBm

    dBm is a power measurement and is the decibal of the power in mW.


    dBm=10\log \left ( mW \right )

    dBuW

    dBuW is a power measurement and is the decibal of the power in uW.


    dBm=10\log \left ( \mu W \right )

    dBuW EMF

    dBuW EMF is a power measurement and is the decibal of the power in uW. In a system with no termination or load.


    dBm=10\log \left ( 2\cdot \mu W \right )

    dBuW PD

    dBuW PD is a power measurement and is the decibal of the power in uW. In a system with a matched load.


    dBm=10\log \left (\mu W \right )

    dBpW

    dBpW is a power measurement and is the decibal of the power in pW.


    dBm=10\log \left ( \mu W\cdot 1e6 \right )

    dBpW EMF

    dBpW EMF is a power measurement and is the decibal of the power in pW. In a system with no termination or load.


    dBm=10\log \left ( 2\cdot \mu W\cdot 1e6 \right )

    dBpW PD

    dBpW PD is a power measurement and is the decibal of the power in pW. In a system with a matched load.


    dBm=10\log \left (\mu W\cdot 1e6 \right )
