We report on cooperative quantum cutting in Tb^3+- Yb^3+ codoped glass ceramics. Precipitation of BaF2 nanocrystals is confirmed by XRD and HRTEM analysis. Near-infrared emission due to transition of Yb^3+ ions und...
A new architecture of CMOS low voltage downconve rsion mixer is presented.With 1.452GHz LO input and 1.45GHz RF input,simulation results show that the conversion gain is 15dB,IIP3 is -4.5dBm,NF is 17dB,the maximum tra...
