Keywords:Long Term Evolution (LTE), Cascode LNA, Double Feedback Technique
The paper aims to develop a new cascode low noise amplifier (LNA) by using double feedback technique architecture for wireless communication especially for long term evolution (LTE). The objective of this article is to display the improved performance of gain by minimizing noise figures with innovative techniques for the realization of Long Term Evolution (LTE). The innovation technique with implementation double feedback technique architecture outlines the possibility to improve the performance in various parameters such as bandwidth, stability, gain, noise figure, power consumption and complexity. The realization using cascode LNA is verified by using FHX76LP Super Low Noise HEMT that operate at 5.8 GHz in compliant with LTE standard. The Advance Design System (ADS) software is used to obtain characteristics for collecting data in a smith chart and s-parameter generated by simulation. The cascode LNA with the double feedback technique achieves an average gain of 20.887 dB with a noise figure of 0.341 dB. The input return loss and output return loss are – 14.354 dB and – 11.879 dB respectively. The outcome of this work will contribute to providing a better wireless signal receiver especially for the LTE standard and it potentially addressing wireless communication issues in rural areas.
