Publication number: 20240063841Abstract: 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.Type: ApplicationFiled: June 28, 2022Publication date: February 22, 2024Inventors: Thomas Edward Voor, Jeffrey L.

Patent number: 10763781Abstract: 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.Type: GrantFiled: June 29, 2018Date of Patent: September 1, 2020Assignee: Silicon Laboratories Inc.Inventors: Thomas Edward Voor, Jeffrey A.
