Abstract

A wireless data communication device is disclosed. A millimeter range mixer having a first immediate frequency port, a second reference port, and a millimeter wave port receives an intermediate frequency radio signal. A local oscillator source provides a reference signal to the reference port of the mixer, and using a millimeter wave filter coupled to the millimeter wave port of the mixer, an intermediate frequency radio signal is converted to a millimeter wave frequency signal and a millimeter wave frequency signal is converted to an intermediate frequency radio signal.

Claims

1. A wireless data communication device comprising:

a millimeter range mixer having a first intermediate frequency port, a second reference port, and a third millimeter wave port;

an oscillator for providing a reference signal to the reference port of the mixer; and

,

a millimeter wave filter coupled to the millimeter wave port of the mixer for converting an input intermediate frequency radio signal to a millimeter wave radio signal and for converting a millimeter wave radio signal to an output intermediate frequency radio signal.

2. The device of claim 1, further comprising a power amplifier for amplifying the strength of the radio signal.

3. The device of claim 1, further comprising a low noise filter for amplifying the strength of the input radio signal.
