Control of configurable receiver front end module based at least in part on signal metric information

A non-transitory storage medium comprising instructions that, when executed, cause a device to perform a method comprising:

• comparing, in a comparator of the device, a signal level of a receive radio frequency (RF) signal to a first threshold, the receive RF signal obtained from a controllable location in an RF front end circuit;
• and
• in response to the signal level of the receive RF signal exceeding the first threshold, causing the RF front end circuit to be reconfigured from a first mode in which an input to a low noise amplifier (LNA) is coupled an antenna to a second mode in which the input to the LNA is coupled to an RF filter.
