Design of ultra wideband low noise amplifier with the negative feedback using micro strip line matching structure for multiple band application and its simulation based performance analysis

In this paper we have discussed the design of multiple band low noise amplifier using micro strip lines structure and its simulation based performance analysis. LNA design is very difficult work in the receiver part because the signal which received is very weak and gets affected easily with the noise. Therefore it is necessary that new design must give noise figure as low as possible over a wide range. If LNA works for on wide band so it can be used for multiple band applications. Its simulation based analysis is also important to test its stability and performance before fabrication. As it is difficult to get all the characteristics of LNA perfectly therefore there is always a tradeoff between gain and noise. We have to optimize the values of the component so as to get the optimum results. To achieve this entire component, the negative feedback is used with a matching circuit which consists of micro strip line and some passive elements. The software ADS is used for simulations and to optimize design. The simulation based performance analysis done with variation of temperature. In results we are getting the Gain of LNA up to 30 db with noise figure less than 3 db. Stability that is getting for design LNA is greater than 1 for frequency band of 500 MHz to 6 GHz Design LNA can be used for multiple band applications like GSM, Bluetooth, CDMA,WiFi, WiMax & GPS.
