| Summary: | This paper describes the design of wideband low noise amplifier (LNA) for mobile software defined radio (SDR) application which
targeted to be applied in two-way communication mobile system architecture. The technical specification was deduced from the TIA-
603C standard receiver system sensitivity and intermodulation. The proposed LNA exhibit low power consumption and adopts a negative
feedback wideband amplifier topology, operated from 100 MHz to 1 GHz which covers the whole Land Mobile FM Communication
Equipment (136 941 MHz) frequency band. The proposed topology solve the RF tracing problem inherited in the targeted frequency
and also the problem of economically impractical PCB size rendered by other wideband amplifier methods. The Advanced Design System
software is used to perform the simulations. The measured result show the proposed LNA has a stable gain of more than 15 dB, noise
figure less than 1.5 dB, S11 and S22 less than -10 dB, with current consumption of 8 mA from voltage supply at 1.8 V. |
