A particular apparatus for generating a local oscillator (LO) signal includes a phase-locked loop (PLL) configured to output a signal having a frequency that is a sub-harmonic of a LO frequency. The apparatus also includes a mixer block having a frequency upconverter configured to upconvert the signal to generate a LO signal having the LO frequency. For example, the PLL may be integrated into a multiple-input multiple-output (MIMO) device and may generate the sub-harmonic signal. The sub-harmonic signal may be routed to each of a plurality of mixer blocks of the MIMO device. Each of the mixer blocks may upconvert the sub-harmonic signal to generate the LO signal. |
