Abstract
An RF front-end system is formed to include tunable frequency converters within the transmit and receive sections of each channel, allowing for conventional, limited-bandwidth wireless devices to transmit and receive a broad range of frequencies. Both the transmit and receive sections use superheterodyne frequency conversion to provide the translation between the limited frequency band associated with conventional wireless devices and wide frequency band (e.g., between about 100 MHz and 7000 MHz) approved for wireless communication. By virtue of using a local oscillator that can be widely tuned over the complete available frequency spectrum, the up-converted signals used for transmission can be expanded over this wider frequency selection.
