Abstract
An apparatus includes a first magnetic resonance (MR) coil element configured to output a first set of MR data at a first output frequency and a first mixer coupled to the first MR coil element. The first mixer is configured to receive the first set of MR data from the first MR coil element and frequency translate the first set of MR data to a first offset frequency different from the first output frequency by a first offset value. The apparatus also includes a digitizer coupled to the first mixer and configured to convert the frequency-translated first set of MR data into a set of digital data and a transmission line coupled to the first mixer and to the digitizer, the transmission line configured to transmit the frequency-translated first set of MR data from the MR coil element to the digitizer without a balun coupled to the transmission line.
