Why is return loss important for low-noise amplifiers?

Low-noise amplifiers are used to amplify weak signals. If the return loss of an LNA is too low, some of the amplified signal will be reflected back to the input of the amplifier. This can cause distortion and interference, and it can also reduce the overall gain of the amplifier.

How to Calculate Return Loss of Low-Noise Amplifier?

Return Loss of Low-Noise Amplifier calculator uses Return Loss = modulus((Input Impedance-Source Impedance)/(Input Impedance+Source Impedance))^2 to calculate the Return Loss, The Return Loss of Low-Noise Amplifier formula is defined as a measure of how well the amplifier matches the impedance of the source and load. A good impedance match is important for minimizing signal reflection and maximizing power transfer. Return Loss is denoted by Γ symbol.
