LOW NOISE AMPLIFIERS

designs built to your specifications

In radio receivers, picking faint signals out of the ubiquitous background noise requires low noise amplifiers that maintain an acceptable signal-to-noise ratio. These amplifiers are low power devices that use special matching circuits and low-noise active elements that are placed as close to the receiving antenna as possible. Generally, low noise amplifiers become useful above 30-50MHz. Below 30MHz, external noise and interference dominate the radio channel. At UHF and above, the use of low noise amplifiers in receivers is essential.

Most of our low noise amplifier designs use discrete and integrated solutions from UHF to Ka band. In many cases, in L-band and above, the LNA is directly integrated in the antenna for use in navigation, communications and radar applications.
