Q

What is the peak-to-peak RF voltage on the 50 ohm output of a 100 watt transmitter?

🔍 Key Concepts

• Relationship between RF power, RMS voltage, and resistance in a load (Ohm's Law and power formulas) • Conversion from RMS voltage to peak and peak-to-peak voltage for a sine wave • How a 50 ohm resistive load affects the RF voltage for a given power level

💭 Think About

• First, find the RMS voltage developed across a 50 ohm load when 100 watts of power is delivered. Which basic power formula connects these three quantities? • Once you know the RMS voltage, recall the mathematical relationship between RMS and peak voltage for a pure sine wave. How do you convert RMS to peak? • From the peak voltage, how do you obtain the peak-to-peak voltage? What simple multiplication is involved?

✅ Before You Answer

• Use P = V^2 / R to solve for V_rms across a 50 ohm load at 100 W • Remember that for a sine wave, V_peak = V_rms × √2 and V_pp = 2 × V_peak • Double-check units and arithmetic: square roots, multiplication by √2, and doubling for peak-to-peak voltage
