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
S95029B
-
The S95029B noise figure application enables high-accuracy noise figure and noise-power measurements of amplifiers, frequency converters, and mixers by using the Keysight vector-source-correction technique. Using a source-impedance tuner to remove the effects of imperfect system-source match, this technique produces higher accuracy results than Y-factor method and other cold-source implementations--especially for in-fixture, on-wafer, and automated-test environments.
