Claim Text:
1. A frequency translation device, comprising: a transmit circuit including a first frequency converter configured to receive an RF signal at a first RF frequency from a wireless communication device that is separate from the frequency translation device and to convert the signal at the first RF frequency into a signal at one of a plurality of second RF frequencies; a receive circuit including a second frequency converter configured to convert a signal at the one of the plurality of second RF frequencies into a signal at the first RF frequency and to send the converted RF signal at the first RF frequency to the wireless communication device that is separate from the frequency translation device; a detector circuit configured to determine when the frequency translation device is receiving a signal, and to route the signal to the transmit circuit or to the receive circuit; a frequency reference circuit including a phase locked synthesizer configured to provide a selectable reference signal to the transmit circuit and receive circuit, wherein the selectable reference signal determines which one of the plurality of second RF frequencies is used by the transmit circuit and the receive circuit; an antenna; a first relay adapted to connect the antenna to the transmit circuit or the receive circuit; a splitter; and a second relay adapted to connect the splitter to the transmit circuit or the receive circuit; wherein the splitter is configured to split a signal between the detector circuit and the transmit circuit; and wherein the detector circuit includes a radio-frequency detector, a comparator electrically connected to the radio-frequency detector, and a first and second relay drivers electrically connected to the comparator and in communication with the first relay and the second relay, respectively.
