Low noise amplifiers are one of the basic building blocks of any communication system. The low noise amplifier amplifies weak signals captured by an antenna. Moreover, low noise amplifiers are used in different application such as cellular phone, cordless phone, Wi-Fi systems and GPS system among others to increase the operation efficiency of these products. The purpose of such amplifiers is to amplify the received signal to acceptable levels with minimum self-generated additional noise. A low noise amplifier is commonly located close to detection device to reduce losses in feed line. In radio frequency front-end devices, the radio frequency signals received from the antenna are amplified by low noise amplifier and then down converted by the mixer to be low frequency signals. For a global positioning system receiver when signal travels wirelessly and it arrives at the receiver, it has some noise in the signal that affects the information being carried by the signal. Using low noise amplifier at the radio frequency front end of receiver is the best way to reduce the noise beside to ensure system efficiency and data accuracy. In every radio frequency receiver system, low-noise amplifiers can be used to improve the signal-to-noise ratio. It is a key module of a GPS front-end. The low noise amplifier basically performs multiple operations such as weak signal amplification, reduction of noise, increased gain, high stability, reduce noise figure and eliminates channel interference.
Superior performance levels,increased efficiency, achieving lowest possible noise figure , increasing demand for GPS for navigation across the globe ,demand for low cost high quality products and rising installation of low noise amplifier across various applications are primary factors driving the global GPS low noise amplifier market. Such beneficial features and increasing uses are generating the market demand which is expected to dominate the GPS low noise amplifier market. The power levels of satellite signals received by a GPS receiver is quite low. This poses a challenge on the sensitivity of the system and a low noise amplifier with low noise figure and high gain can boost the sensitivity. Such amplifiers maintains optimal GPS signal reception for as long as possible. GPS low noise amplifier provides a cost effective way to make improvement in the reliability of GPS signal reception. Despite the fact a larger ground antenna can give a better as well as a strong signal, this solution can be very costly than simply adding a low noise amplifier. Such an amplifier helps to improve the antenna signal in order to compensate for the feed line losses going from the antenna to the receiver.
