What is a Low Noise Amplifier?
A low noise amplifier is an electronic amplifier which is used in order to amplify possibly weak signals such as those received by an antenna. Low noise amplifiers are usually located very close to the detection device in order to reduce losses in the feed line. A low noise amplifier is a key component placed at the front end of a radio receiver circuit. By using a low noise amplifier, the effect of noise from subsequent stages of the receiving chain is diminished by the gain of the amplifier.
Types of Low Noise Amplifiers
There are many different kinds of low noise amplifiers and at Future Electronics we stock many of the most common types categorized by nominal gain bandwidth, maximum input offset voltage, maximum supply voltage, nominal slew rate, packaging type and number of channels. The parametric filters on our website can help refine your search results depending on the required specifications.
The most common sizes for nominal gain bandwidth are 3 MHz, 4 MHz and 10 MHz. We also carry low noise amplifiers with nominal gain bandwidth as high as 12 GHz. The number of channels can be between 1 and 4, with the most common low noise amplifier semiconductor chips having 2 channels.

Applications for Low Noise Amplifiers:
Low noise amplifiers are used in various applications such as ISM radios, cellular and PCS handsets, wireless LANs, wireless Data, GPS receivers, cordless phones and automotive remote keyless entry devices. They are also found in satellite communication systems, where the ground station receiving antenna will connect to a low noise amplifier. This amplifier is needed due to the weakness of the signal being received. Although a larger ground antenna would give a stronger signal, such a solution is much more costly than simply adding a low noise amplifier. The amplifier boosts the antenna signal in order to compensate for the feed line losses going from the antenna to the receiver.
