ABSTRACT:
A method for single side band transmissions begins by mixing, in a current domain, an in-phase component of outbound formatted data with an in-phase component of a local oscillation to produce a first mixed signal. The method continues by mixing, in the current domain, a quadrature phase component of the outbound formatted data with a quadrature component of the local oscillation to produce a second mixed signal. The method continues by summing the first and second mixed signals to produce a radio frequency signal. The method continues by amplifying the radio frequency signal prior to transmission.
