| Popis: | A mixer-first receiver enhanced with capacitive positive feedback is proposed to obtain a steeper filter roll-off and enhanced linearity, while keeping low noise figure. It covers all sub-6GHz cellular bands and achieves a high IIP3 of +39dBm and blocker 1dB gain compression point of +12dBm for a blocker frequency-offset of 80MHz at f LO =2GHz. The NF ranges from 2.4dB at f LO =1GHz to 5.4dB at f LO =6GHz. The chip has been fabricated in Globalfoundries 45nm SOI technology on a high resistivity substrate. |
