Apparatus and method for a multi-band radio operating in a wireless network

摘要

A multi-band radio operates in a wireless network. The multi-band radio includes a receiver configured to receive a signal. A switch in the receiver is configured to route a signal having a frequency within a first band of frequencies to a first path and a second band of frequencies to a second path. A mixer in the receiver is positioned along the second path. The mixer in the receiver configured to convert a signal having a frequency within the second band of frequencies into a signal having an intermediate frequency within the first band of frequencies.
