Abstract

A method and system is described for several embodiments of a communication system. In a first embodiment, a method and system is described wherein a signal is received and down-converted and wherein power consumption can be characterized as 'ultra-low.' In a second embodiment, a method and system is described wherein undesirable images are rejected in a down-conversion system. In a third embodiment, a method and system is described for directly down-converting analog FM signals and digital FM signals to demodulated baseband information signals. In a fourth embodiment, a method and system is described wherein a signal is transmitted in a highly efficient manner. In a fifth embodiment, the present invention is directed toward a multi-band communication system that can transmit and/or receive one or more information signals on one or more transmission frequencies using one or more modulation schemes. The receiver and transmitter operate in a plurality of modes, including but not limited to a single band/channel mode, and a multiple band/channel mode. The receiver and transmitter may operate separately or as part of a transceiver. According to embodiments of the invention, the frequency translation is implemented using a universal frequency translator (UFT). In the aforementioned embodiments, the invention is used in a family radio service (FRS) unit, although the invention is not limited to this embodiment.
