Local oscillator (LO) generation for carrier aggregation in phased array front ends

A wireless device, comprising:

• a plurality of transceiver chains;
• processing circuitry;
• and
• a memory configured to store executable instructions that, when executed by the processing circuitry, causes each transceiver chain from the plurality of transceiver chains to:
• generate a first reference signal having a first frequency;
• generate, via a digital to time converter (DTC), a second reference signal based upon the first reference signal, the second reference signal having a second frequency that is a fractional multiple of the first frequency;
• generate, via a high-band (HB) injection locked frequency multiplier (ILFM), one or more HB local oscillator (LO) signals having a HB LO frequency that is based upon the first frequency associated with the first reference signal;
• and
• generate, via a low-band (LB) ILFM, one or more LB local oscillator (LO) signals having a LB LO frequency that is based upon the second frequency associated with the second reference signal.
