Single-ended low noise multiband LNA with programmable integrated matching and high isolation switches
This paper describes a novel 90nm single-ended multiband input LNA preceded by RF input switches connected to an on-chip balun intended to drive a differential mixer. The architecture achieves a low noise figure of 1.8dB. The advantage with the proposed architecture is that it is fully single-ended with on-chip programmable narrow-band matching eliminating the need of off-chip components. Especial
