A universal frequency translation module (UFT) frequency translates an
electromagnetic (EM) input signal by sampling the EM input signal
according to a periodic control signal (also called an aliasing signal).
By controlling the relative sampling time, the UFT module implements a
relative phase shift during frequency translation. In other words, a
relative phase shift can be introduced in the output signal by sampling
the input signal at one point in time relative to another point in time.
As such, the UFT module can be configured as an integrated frequency
translator and phase-shifter. This includes the UFT module as an
integrated down-converter and phase shifter, and the UFT module as an
integrated up-converter and phase shifter. Applications of universal
frequency translation and phase shifting include phased array antennas
that utilize integrated frequency translation and phase shifting
technology to steer the one or more main beams of the phased array
antenna.
