Zs, SNR is something that depends on your signal. We can't tell you what signal you have. The number I can give you is the Noise Figure of the SBX at room temperature. It's something that depends on both gain and frequency. You can find the measurement data under [1]. Together with the normal thermal noise power spectral density and your receiver bandwidth, you can calculate a maximum SNR. Also take quantization noise into account, and don't forget that you're oversampling. All these effects depend on how you parameterize your transmission.
