Wideband Low Noise Amplifier for Next Generation Wireless RF Frontend: A Review Paper

Abstract

The volatile growth of the wireless industry, global access to the internet, and the ever increasing demand for high speed
data communication are encourage us toward rapid developments in communication technology. Wireless
communication plays an essential role in this transformation to the next generation of communication systems. Next
generation wireless terminal should support multiple communication standards with different modulation scheme require
wideband Radio Frequency (RF) frontend having high gain, low noise figure (NF), good linearity and low power
consumption. This can be done using software define radio (SDR) architecture. In SDR architecture of receiver Low
Noise Amplifier (LNA) is essential part. In this paper we done meticulous survey of wideband LNA topologies published
in open literature suitable for SDR. Measured results of the sample LNA designs from each category are tabulated and
discussed with emphasis on gain, NF, input matching, power consumption, and linearity tradeoffs. At the end discuss
design challenges of next generation RF frontend wideband LNA.
