Designing Ultra Wideband Low Noise Amplifier

Abstract

     This text reveals the configuration of a low noise amplifier for ultra-wide bands (UWB LNA). A symmetrical 3D RF integrated inductor was used to create the proposed UWB LNA which extends its bandwidth from 2.5 GHz to 16 GHz. This UWB LNA gains from the proposed LNA with an overall performance range of 6 dB-18 dB and -12 dB to 0 dB in low output mode and a bandwidth of –3 dB of 2 GHz. In the high gain setting mode, the noise figure (NF) is 3.5-4.5 dB. In a high-gain mode the planned LNA is 6 dB-18 dB and in a low-gain mode, -12 dB to 0 dB and a bandwidth-3 dB is 2 GHz. In high gain mode, the noise (NF) number is 3.5-4.5 dB.
