Check rf 100 receiver.

Mar 17, 2021 · So for example a receiver sensitivity of -90 dBm is better than -80 dBm i.e this means that the -90 dBm receiver is more sensitive and can interpret lower power signals. The typical range for receiver sensitivity of various RF modules is from -50 to -100 dBm. Different standards and technologies have different requirements for receiver sensitivity.
