1、The heterodyne receiver architecture was ruled out due to the need of off-chip image rejection filters which opposes the goal of a low-cost application where direct antenna coupling is preferred.
2、A traditional RF front-end consists of an LNA followd by I and Q mixers driven by I and Q LO signals ,respectively.(LO本季振荡器)
3、A microphotograph of the 5.77mm² die is shown in Fig.14.(图表14)(die如何理解?)
