Abstract


This paper present the design of an high-gain low-noise amplifier (LNA) in the application of base station receiver very high frequency omnidirectional range (VOR) for ground check monitoring. VOR is within the 108–118 MHz frequency band. LNA serves as an essential part of radio receiver systems. It amplifies a very-weak signal captured by an antenna by adding a little noise and minimizing signal distortions. LNA comes with some specifications to which attention should be paid, namely, stability, noise figure, gain, return loss, and bandwidth. The design in this research employs lumped components. The LC tank resonator designed resonates at a center frequency of 113.0 MHz with the 2SC3583 transistor, with small-signal amplifier characteristic highly suitable for LNA application over the VHF band. DC bias use the collector feedback biasing configuration. It is hoped that the amplifier works in class A. The results of the simulations at the center frequency of 113.0 Mhz. This design has desirable parameters satisfying the design specifications and will be applicable to VOR base station receiver equipment for ground check monitoring at the laboratory of Civil Aviation Academy.
