摘要: A self-embedded power-recycling technique in microwave mixers is proposed and presented for radio frequency (RF) multiple-input multiple-output (MIMO) systems. The novelty of the stems from a distinct concept harnessing direct current (dc) signal rectified by mixing elements course translation. large-signal model nonlinear element coupled with electromagnetic simulations used to understand examine contribution dc overall transceiver energy efficiency. single-balanced (SB) diode-switching mixer integrated diplexer bank prototyped using off-the-shelf components validate technique, which can be extended an IC implementation. measurement results show that about 30% driving power directly present form at port under maximum conversion efficiency condition. Furthermore, wide linear instantaneous bandwidth performance shown resistive termination sum–product downconverter.
