Frequency translation device and wireless communication system using the same

摘要

A frequency translation device includes a transmit circuit including a first frequency converter configured to convert a signal at a first frequency into a signal at a second frequency. A receive circuit includes a second frequency converter configured to convert a signal at the second frequency into a signal at the first frequency. A detector circuit is 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.

主权项

1. A frequency translation device, comprising:
a transmit circuit including a first frequency converter configured to wirelessly receive a 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 wirelessly send the converted 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; and 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.
