A wireless communication device can include chains of circuitry, with at least one chain being a chain of transmitter circuitry to generate output radio frequency (RF) signals using baseband signals and at least one chain of receiver circuitry configured to receive RF signals. At least one chain can include a plurality of circuit blocks, a circuit block including at least one of oscillator circuitry, clocking circuitry, and phased lock loop (PLL) circuitry. The apparatus can include interconnect circuitry configured to couple one of the plurality of circuit blocks to a respective chain. Other systems, methods and apparatuses are described.
