A SAW-less discrete-time superheterodyne receiver (RX) with multi-stage harmonic rejection in 28nm CMOS, featuring highly linear LNTA, employs a novel blocker-resilient octal charge-sharing band-pass filter to achieve low power consumption. The RX features NF of 2.1 to 2.6dB, and IIP3 of 8 to 14 dBm, while drawing only 24 to 37 mW in different operation modes.
