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.
