Low Noise Amplifiers
Our range of ITAR Free, Low Noise Amplifiers (LNAs) cover a variety of applications but are primarily suited to airborne, maritime and ground based radar systems. LNAs are primarily intended to minimise added noise whilst providing high gain so design focusses on the parameters associated with the noise response of the amplifier. They are usually the first amplifier in the Radar detection chain and will have the lowest noise figure.

Noise Figure Measurements With Vector Correction
S96029B
This software application enables high-accuracy noise figure and noise-power measurements of amplifiers. It utilizes Keysight’s unique vector-source-correction technique, which uses a source-impedance tuner to remove the effects of imperfect system-source match. This approach yields accuracy that surpasses that provided by the Y-factor method and other cold-source implementations, especially for in-fixture, on-wafer, and automated-test environments. A scalar-calibrated method is also available that offers less accuracy but is faster and does not require an impedance tuner.
