A frequency transverter (10) and method for enabling bi-frequency dual-directional
transfer of digitally encoded data on an RF carrier by translating between a crowded
or otherwise undesirable first frequency band, such as the 2.4 GHz ISM band, and
a less-crowded or otherwise desirable second frequency band, such as the 5.0 GHz-6.0
GHz U-NII band. In a preferred embodiment, the transverter (10) connects
between an existing data radio (11) and its existing antenna (30),
and comprises a bandswitch (12); an input RF isolating device (14);
a transmuter (16); a converter (18); a dual output local oscillator
(20); an output RF isolating device (22); and an antenna (24)
tuned to the second frequency band. The bandswitch (12) allows for bypassing
the transverter (10), thereby facilitating its use with legacy systems.
The transmuter (14) and converter (16) are adapted to convert to
and from, respectively, the second frequency band.
