Abstract
Systems, methods, and circuitries are provided for a local oscillator (LO) signal distribution. An exemplary LO distribution network includes a common LO buffer configured to buffer an LO signal, a receive (RX) LO buffer, and a transmit (TX) mixer in a cascaded arrangement. The RX LO buffer is configured to receive the LO signal and buffer the LO signal and to provide the LO signal to an RX mixer. A first LO signal line and a second LO signal line are configured to conduct the LO signal from the common LO buffer to the RX LO buffer. The RX LO buffer is coupled to the first LO signal line and the second LO signal line. The TX mixer is also coupled to the first LO signal line and the second LO signal line.
