Dual band wireless local area network (WLAN) transceiver. A wireless communication device includes at least two different transceivers (or radios) therein to effectuate communications with other wireless communication devices using at least two respective frequency bands. Each of these two transceivers may have different respective circuitry (e.g., each may have a different respective power amplifier (PA) and/or other circuitry components). Coordination is made regarding when certain components of one transceiver turn on and operate when another transceiver may be transmitting or receiving communications. For example, the turn on of a PA and/or other circuitry components (e.g., such as components using or requiring high current) within one transceiver can be coordinated as to minimize deleterious effects regarding the operation of another transceiver. Moreover, latency existent within each of the respective transceiver chains within the wireless communication device (e.g., including baseband and radio portions) is accounted for regarding their respective concurrent operation.
