Abstract
In one embodiment, a local oscillator (LO) is configured to generate an LO signal. A transmission line receives the LO signal from the local oscillator and transmits the LO signal. A first set of taps and a second set of taps tap the transmission line to receive the LO signal. A plurality of transceiver blocks are configured to receive and transmit a plurality of phase-shifted radio frequency signals. Each transceiver block is coupled to a first tap and a second tap. Each LO signal received for a transceiver block is received with a different phase. However, the same reference phase may be calculated from a first LO signal received from the first tap and a second LO signal received from a second tap. Each transceiver block receives the reference LO signal having the reference phase determined from the first LO signal and the second LO signal.
