Abstract: Embodiments of a reference path circuit and communication device are generally described herein. The reference path circuit may include an injection locked multiplier (ILM) and a group of one or more buffer amplifiers. The ILM may receive a sinusoidal reference signal from a reference oscillator at a reference frequency. The ILM may generate a sinusoidal ILM output signal at an ILM output frequency that is based on an integer multiple of the reference frequency. The integer multiple of the reference frequency may be within a locking range of the ILM that may be based on a resonant frequency of the ILM. The group of one or more buffer amplifiers may generate an output clock signal for input to the frequency synthesizer. The output clock signal may be based on a sign function of the ILM output signal.

Abstract: Embodiments pertain to systems, methods, and component devices for Tx-Tx transmit concurrency by combining signals before power amplification. One example embodiment includes validity check circuitry configured to check a transmission power for a Bluetooth signal against a first threshold transmission power, a Bluetooth Power Amplifier, and a WLAN power amplifier. A switching network controlled by the validity check circuitry and configured to couple the Bluetooth input to Bluetooth power amplifier input when the transmission power for the Bluetooth signal is above the first threshold transmission power and to couple the Bluetooth signal with a WLAN signal for input to the shared WLAN power amplifier when the transmission power for the Bluetooth signal is less than the first threshold transmission power.
