Estimating noise figure of matching networks for low-input-impedance preamplifiers

The noise figure of a matching network between an MRI receive coil and a preamplifier with low input impedance can be adequately accurately estimated with relationship F≈1+R11/Rc. It is demonstrated how to use this relationship to choose optimal in terms of signal-to-noise ratio (SNR) matching and decoupling network topology. The formula as an efficient tool to estimate noise figure of matching networks and is useful in low-field and high-coil-Q applications, where the noise of the matching network becomes comparable to the coil noise.
