Patent ID: 7024165

Claim:
A transverter operable to translate a transmit signal and a receive signal between a first frequency band and a second frequency band, wherein the transverter is connected between a data radio and an existing antenna tuned to the first frequency band, the transverter comprising: a bandswitch interposed between the data radio and the existing antenna and adapted to allow for selectively directing the transmit signal from the data radio to the existing antenna, thereby substantially bypassing the transverter; an input isolating device connected to the bandswitch and adapted to electrically isolate one or more components of the transverter from the data radio; a transmuter connected to the input isolating device and adapted to translate the transmit signal from the first frequency band to the second frequency band; a converter connected to the input isolating device and adapted to translate the receive signal from the second frequency band to the first frequency band; a dual output local oscillator connected to both the transmuter and the converter and adapted to provide a drive level thereto; an output isolating device connected to both the transmuter and the converter and adapted to electrically isolate the transverter; and an antenna connected to the output isolating device and tuned to the second frequency band and adapted to transmit the transmit signal and to receive the receive signal, wherein the input isolating device and the output isolating device are each a Y-junction ferrite device configured as a three-port circulator device adapted to provide a non-reciprocal effect, and wherein the input isolating device and the output isolating device each exhibit a third order symmetry behavior.
