A Low-Power 2.4GHz CMOS Receiver Front-End Using BAW Resonators

A low-power 2.4GHz heterodyne receiver front-end is integrated in 0.18μ;m CMOS using BAW solidly mounted resonators. The resonators with Qs of up to 580, provide both impedance matching and selectivity. An image rejection of up to 50dB, a NF of 11dB and IIP3 of -16.1dBm with a power dissipation of 1.8mW are demonstrated
