Receiver Sensitivity Calculator

What is Receiver Sensitivity?

Receiver sensitivity is the minimum input signal power level required for a receiver to produce a specified output signal level, typically measured in dBm. It's a critical parameter in wireless communication systems as it determines the weakest signal that can be reliably detected.

How to Use the Calculator

1. Enter the output power of your receiver in dBm (e.g., -90 dBm).
2. Input the noise figure of your receiver in dB (e.g., 5 dB).
3. Specify the bandwidth of the receiver in MHz (e.g., 20 MHz).
4. Click the "Calculate" button to compute the receiver sensitivity.

Principle of Calculation

The calculator uses the following formula to determine receiver sensitivity:

Sensitivity (dBm) = Pout - NF - 10log(BW)

Where:

• Pout is the output power in dBm
• NF is the noise figure in dB
• BW is the bandwidth in MHz

Practical Applications

Receiver sensitivity is crucial in various applications including:

• Designing wireless communication systems
• Comparing receiver performance
• Evaluating system performance in noisy environments
• Ensuring adequate signal strength for reliable communication
