Hence, findings from this paper suggest the use of single stage LNA designed using Darlington pair in transceiver satellite applications. Q2: Using Smith Chart (Proper Working on Smith Chart) CALCULATE standing wave ratio, reflection coefficient magnitude, and return loss values to complete the entries in the following table: (One line explanation is needed how you find SWR, Reflection Coefficient and Return Loss.) SWR ir RL (dB) 0.00 1.00 1.01 0.01 1.05 30.0 1.10 1.20 0.10. Here, LNA designed using darlington pair shows low NF of 3.3-4.8 dB, which comparable to other reported single stage LNA designs and appreciably low compared to the three stages LNA. In this paper, single stage LNA has shown the 23 dB measured gain, while the three stages LNA has demonstrated 29 dB measured gain. Here, the phase mismatch between these patameters is quantitavely analyzed to study the effect on gain and noise figure (NF). This paper is focused on to make comparison of three stage and single stage LNA. This LNA has been fabricated on 90nm CMOS process. This paper shows the schematic of LNA by using Darlington pair amplifier. This paper reports on with analysis of wideband LNA. The design concept demonstrates the design trade off with NF, gain, power consumption.

The demand of low noise amplifier (LNA) has been rising in today's communication system. © 2018 Institute of Advanced Engineering and Science. The aim of this paper was to examine the power consumption patterns of the main elements in the BS, employ various techniques to reduce their power consumption, reduce the operational cost and improve the efficiency of the BS. The BSs are the major consumers of energy in the wireless communication network due to the use of inefficient power amplifiers and therefore deploying more BSs into the network will increase the power consumption and the networks operational cost. The network operators in trying to meet this increasing demand injected more access points by deploying more Base Stations (BSs) to make the network denser. This expansion has created an increase in the demand for high speed internet, multimedia messaging services, digital broadcasting etc, thus fuelling higher data traffic. Machine-to-Machine (M2M) communication over the Long Term Evolution Advanced (LTE-A) networks has witness exponential growth and expansion in the last couple of years.
