Link Budget Equation Calculator

Formula

The formula to calculate the Link Budget Equation is:

\[ RP = TP + (G - L) \]

Where:

\(RP\) is the Link Budget Equation (dBm)
\(TP\) is the transmitted power (dBm)
\(G - L\) is the gains minus losses (dB)

What is Link Budget Equation?

The Link Budget Equation is used to calculate the received power at the end of a communication link. It takes into account the transmitted power, gains from amplifiers and antennas, and losses due to propagation, absorption, and other factors. Understanding the link budget helps in designing efficient communication systems and ensuring that the received signal is strong enough for reliable data transmission.

Example Calculation

Let's assume the following values:

Transmitted Power (TP) = 10 dBm
Gains minus Losses (G-L) = -20 dB

Using the formula:

\[ RP = 10 + (-20) = -10 \text{ dBm} \]

The Link Budget Equation (RP) is -10 dBm.
