摘要
Systems for a dual-band transceiver that re-uses a lower frequency transmitter to drive a local oscillator (LO) for high frequency circuits are disclosed herein. The need for a LO lineup requiring high frequency and high power is eliminated. The output of a lower frequency band is modified to be used as a LO drive for the higher frequency band transceiver. Using a carrier recovery loop, the system is operable to simultaneously operate in both bands. The result is a solution that eliminate the design of a high performance LO circuits for a higher band of a mmW dual-band system. This significantly reduces the overall complexity of the system. Furthermore, the inventive architecture reduces the design complexity and overall cost to implement dual-band circuit.
