Abstract :
This paper presents a wideband blocker filtering technique for a RF front-end. The wideband LNA and the transferred impedance filter are implemented as part of a receiver to demonstrate the feasibility of the system. The front-end achieves a gain of 43 and 41 dB, noise figure of 3.2 and 5.7 dB with IIP3 of -13 and -5 dBm with the transferred-impedance filter turned off and on, respectively. Added selectivity of 6 dB is achieved by using the structure described in this paper.
