摘要： 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.

摘要： In one aspect, a method comprises: initializing a front end circuit of a wireless device into a first mode in which a radio frequency (RF) signal processing path comprises a low noise amplifier (LNA) having an output coupled to an RF filter; and in response to an RF signal received in the front end circuit having a level greater than a first threshold, reconfiguring the front end circuit into a second mode in which the RF filter is coupled to an input of the LNA.

摘要： A system and method of performing temperature compensation based on temperature of a crystal. An integrated circuit includes a clock circuit, a memory, an interface developing a sense voltage indicative of a temperature of the crystal, and a controller. The memory stores compensation values including nominal values based on a nominal third order polynomial that defines a nominal frequency versus temperature relationship of a crystal design representing multiple crystals, and a pair of adjustment values derived from two temperature-frequency error points. The controller determines a temperature value based on the sense voltage, calculates a frequency offset using the temperature value and the compensation values to solve a compensated third order polynomial defining a compensated frequency versus temperature relationship of the crystal, and adjusts a clock signal of the clock circuit using the frequency offset. A Wi-Fi device may be optimized for industrial IoT operating within an extended temperature range.

摘要： In one embodiment, an apparatus includes: a transmit path to receive, process and output a transmit radio frequency (RF) signal, the transmit path including a first power amplifier; a receive path to receive, process and output a receive RF signal, the receive path including a first low noise amplifier (LNA); and switching circuitry coupled to the transmit path and the receive path. In a transmit mode, the switching circuitry is to cause a RF filter to couple into the transmit path to filter the transmit RF signal and cause the filtered transmit RF signal to be provided to the first power amplifier and thereafter to an antenna. In a receive mode, the switching circuitry is to cause the receive RF signal to be provided to the RF filter and the first LNA, and thereafter to be provided to a digital processor.

摘要： In one aspect, a method comprises: reconfiguring a front end circuit of a device from a first mode having a receiver radio frequency (RF) signal processing path with a first relative order into a second mode having the receiver RF signal processing path with a different relative order; determining that a timeout period has completed; and reconfiguring the front end circuit from the second mode to the first mode in response to determining that the timeout period has completed.

摘要： 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.
