Final answer:
The AN/PRC-150(C) audio input is measured in two ways: 1.5mV at 150 ohms or 0 dBm. The full rated output is achieved at an impedance of 600 ohms. You can calculate the full rated output at a different impedance using a formula.
Step-by-step explanation:
The AN/PRC-150(C) audio input can be measured in two different ways: 1.5mV at 150 ohms or 0 dBm. The full rated output is achieved at an impedance of 600 ohms. To calculate the full rated output at a different impedance, you can use the formula:
Output(dBm) = Input(dBm) + 20 * log10(Output Impedance/Input Impedance)
For example, if the input is 0 dBm at 600 ohms, and you want to calculate the full rated output at 300 ohms, you would use the formula:
Output(dBm) = 0 + 20 * log10(600/300) = 0 + 20 * log10(2) = 0 + 20 * 0.301 = 0 + 6.02 = 6.02 dBm
