Abstract
An apparatus is provided comprising a first integrated circuit. The first integrated circuit comprises a first element comprising one of a transmit or receive element, an oscillator for providing a first local oscillator signal, a local oscillator output configured to output the first local oscillator signal when activated, a local oscillator input configured to receive a master local oscillator signal when activated; and first switching circuitry for selectively coupling the first element to one of the oscillator and the local oscillator input.
