Abstract: In one aspect, an apparatus comprises a transmit path including a power amplifier to receive, process and output a transmit radio frequency (RF) signal the transmit path comprising a power amplifier. A detection circuit coupled to the transmit path may be configured to: detect, during a first portion of a packet of the transmit RF signal, a level of the transmit RF signal at an input to the power amplifier; and detect, during a second portion of the packet of the transmit RF signal the level of the transmit RF signal at an output of the power amplifier. Based at least in part on the detected level at at least one of the power amplifier input or output, a level of at least one component of the transmit path upstream to the power amplifier is to be updated, to control a transmit power variation of the transmit RF signal.

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.
