Abstract: In one aspect, an apparatus includes a receive path to receive, process and output a receive radio frequency (RF) signal, the receive path comprising at least one low noise amplifier (LNA) and a plurality of signal nodes. The receive path may be configurable to operate in a plurality of modes. The apparatus also may include at least one filter to filter the receive RF signal and at least one detector circuit to detect one or more levels present at one or more of the plurality of signal nodes. The apparatus may configure an order of the at least one LNA and the at least one filter, based at least in part on the one or more levels detected in the at least one detector circuit.

Abstract: In one aspect, a method comprises: comparing, in a comparator, 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.

Abstract: A system and method for detecting and receiving packets that are transmitted over a network that utilizes a plurality of channels is disclosed. The system includes a radio circuit, which can be configured to receive packets over a plurality of channels, a processing unit, and a memory in communication with the processing unit. The processing unit loads a set of operating parameters in the radio circuit, which enables the radio circuit to detect and receive packets on a particular channel. If a preamble is not detected within a predetermined time period, the system hops to a different channel by loading a second set of operating parameters in the radio circuit. This process can be repeated for an arbitrary number of channels.
