Abstract

With rapid expansions of wireless communications, requirements for transceivers that support concurrent multiple services are continuously increasing and demanding design of a concurrent low-noise amplifier (LNA) with low noise figure (NF), high gain, and high linearity over a wide frequency range for various wireless applications. The proposed work focuses on a concurrent multi-band LNA that works at navigational frequencies, namely, of 1.2GHz and 1.5GHz, wireless communication frequencies, namely, of 2.45GHz and 3.3GHz, dedicated short range communication (DSRC) frequency of 5.8GHz for the vehicular communication applications. This circuit has a distinct input matching network which resonates at all desired five frequency bands and is achieved by adapting frequency transformation method. To accomplish simultaneous reception of the desired penta-band, the output matching is designed with simple LC matching network with the aid of load-pull methodology.
