Abstract
A system has a baseband gain stage to receive incoming in-phase and quadrature voltage signals and output in-phase and quadrature current signals, a mixer core arranged to receive the in-phase and quadrature current signals and output radio frequency signals, and a variable gain amplifier to receive the radio frequency signals and produce a broadband radio signal.
