RF Average Power to Peak Power Calculator:
Enter the values of average power, Pave(W) and duty cycle, DC to determine the value of Peak power, PP(W).
RF Average Power to Peak Power Calculator Formula:
Pulsed radio waves in RF signals often come in bursts or pulses, with varying power levels throughout the cycle. This concept relates to the average and peak power of a radio frequency (RF) signal containing pulses.
Peak power, PP(W) represents the highest power level achieved during a single pulse, measured in watts (W). Imagine it as the strongest “burst” of energy.
Average power signifies the overall power output of the RF signal averaged over a specific time period (seconds), also measured in watts (W). Think of it as the “typical” power level considering all the pulses.
Duty cycle value, between 0 and 1 (often expressed as a percentage), represents the fraction of time the signal spends at its peak power compared to the total cycle time (including the time between pulses).
Peak power, PP(W) in watts is calculated by dividing the average power, Pave(W) in watts by duty cycle, DC.
Peak power, PP(W) = Pave(W) / DC
PP(W) = peak power in watts, W.
Pave(W) = average power in watts, W.
DC = duty cycle.
RF Average Power to Peak Power Calculation:
- An RF signal has a average power of 50 watts and a duty cycle of 20%. What is the peak power output?
Given: Pave(W) = 10 W, DC = 20% = 0.2
Peak power, PP(W) = Pave(W) / DC
PP(W) = 50 / 0.2
PP(W) = 250W.
- An RF transmitter has an peak power output of 40 watts and a duty cycle of 5%. What is the average power of the signal?
Given: PP(W) = 40 W, DC = 5% = 0.05
Peak power, PP(W) = Pave(W) / DC
Pave(W) = PP(W) * DC
Pave(W) = 40 * 0.05
Pave(W) = 2W.
