When using the amplifiers in an array configuration, isolation above 20 dB was achieved between neighboring coils by the amplifier decoupling method.  ...  The amplitude information of the radio frequency pulse was added through a customized step-down DC-DC converter with current amplitude feedback that connects to the CMCD stage.  ...  To achieve efficient transmission down the fiber, both RF carrier and envelope were encoded using sigma delta modulation (SDM) [31] .  ...
