This article presents a primary/WuRX which utilizes a quadrature hybrid coupler-based <inline-formula xmlns:mml=\"http://www.w3.org/1998/Math/MathML\" xmlns:xlink=\"http://www.w3.org/1999/xlink\"> <tex-math notation=\"LaTeX\">$N$ </tex-math></inline-formula> -path mixer first architecture to simultaneously achieve low noise, wideband matching, and a shared antenna interface. The passive-mixer first approach and a two-code modulated multi-tone signaling scheme provide interferer tolerance in the WuRX. This article analyzes gain/power tradeoffs in the proposed architecture in the context of noise impact with multi-tone WuRX signaling. The proposed architecture is implemented in 65-nm CMOS and occupies 2.25 <inline-formula xmlns:mml=\"http://www.w3.org/1998/Math/MathML\" xmlns:xlink=\"http://www.w3.org/1999/xlink\"> <tex-math notation=\"LaTeX\">$\\text {mm}^{2}$ </tex-math></inline-formula> .
