“…The Figure 4(a) is the matching network for input matching network port, while the Figure 4(b) is the matching network uses for output port respectively to provider the good performance in term of stability, power gain and S-Parameter. The goals in LNA design are to maximize its gain and minimize its noise figure with sufficient linearity and impedance matching [4], [9], [10], [11]. In order to achieve the key demands for WiMAX receiver characteristics, a LNA is designed should be met are the noise figure less than 3 dB and power gain should be more than 15 dB.…”

Advancement in the wireless industry, internet access without borders and increasing demand for high data rate wireless digital communication moving us toward the optimal development of communication technology. Wireless communication is a technology that plays an important role in current technology transformation. Broadband communication is a method of telecommunication that are available for transmitting large amounts of data, voice and video over long distance using different frequencies. Specifically, Low Noise Amplifier which is located at the first block of receiver system, makes it one of the important element in improving signal transmition. This study was aimed to design a microwave Low Noise Amplifier for wireless application that will work at 5.8 GHz using high-performance low noise superHEMT transistor FHX76LP manufactured by Eudyna Technologies. The low noise amplifier (LNA) produced gain of 16.8 dB and noise figure (NF) of 1.20 dB. The input reflection (S11) and output return loss (S22) are -10.5 dB and -13.3 dB respectively. The bandwidth of the amplifier recorded is 1.2 GHz. The input sensitivity is compliant with the IEEE 802.16 standards.

Software Defined Radio (SDR) or Software Radio is one of the most promising technologies for the mobile and wireless communications. SDR refers to a class of reprogrammable and reconfigurable radios. This paper describes the design of Wideband Low Noise Amplifier (LNA) for SDR receiver's RF Frontend. The proposed Wideband LNA exhibits very low noise figure and high gain over the frequency range of 1.4 GHz to 2.6 GHz. The input and output return loss is found to be less than -10 dB. Also, the amplifier is unconditionally stable over the entire frequency range. This frequency range will cover different standards like Global Positioning System (GPS), GSM-1800, Universal Mobile Telecommunications System (UMTS), Bluetooth etc.

In first stage of each microwave receiver there is Low Noise Amplifier (LNA) circuit, and this stage has important rule in quality factor of the receiver. The design of a LNA in Radio Frequency (RF) circuit requires the trade-off many importance characteristics such as gain, Noise Figure (NF), stability, power consumption and complexity. This situation forces designers to make choices in the design of RF circuits. In this paper the aim is to design and simulate a novel and single Chip consists of a tri-band low noise amplifier (LNA) operating simultaneously at three frequency bands 1.9 GHz, 2.4 GHz and 5 GHz for WLAN, WiFi and WiMax receivers, is designed and presented in this paper. It can be used in many applications of wireless communication (GSM, Zigbee, Bluetooth, Wi-Fi, HiperLAN, UWB, etc ...) for 3G and 4G networks. The proposed circuit is based on two amplifiers, dual-band and simple band, with transistor GaAs FET type ATF 10136 that has a better performance, successful integration of feasibility and a low price compared with other technologies. Simulations of the operation of the amplifier were performed with the software Agilent Advanced Design System (ADS) and Ansoft software and performance of the amplifier were recorded and analyzed. A single stage LNA has successfully been designed with 29.3dB, 24.56dB and 11.93dB with noise figure of 0.44dB, 0.49dB and 4.42dB respectively at three frequency bands 1.9 GHz, 2.5 GHz and 5 GHz.
