Abstract:
1. A transceiver comprising: a local oscillator (LO) configured to generate an LO signal; a transmission line configured to receive the LO signal from the local oscillator and transmit the LO signal; a set of first taps coupled to the transmission line to tap the transmitted LO signal from the transmission line; and a set of second taps coupled to the transmission line to tap the transmitted LO signal from the transmission line; and a plurality of transceiver blocks configured to receive and transmit a plurality of phase shifted radio frequency signals, wherein for each transceiver block in the plurality of transceiver blocks, a first LO signal at a first phase shift is received from a first tap in the set of taps and a second LO signal at a second phase shift is received from a second tap in the set of taps, wherein for each transceiver block in the plurality of transceiver blocks, the received first LO signal at the first phase shift and the received second LO signal at the second phase shift are combined to determine a reference LO signal having a third phase shift, and wherein each reference LO signal determined for each transceiver block has the third phase shift.
