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.

Two Channel Phase and Amplitude Noise Analyzer
DCNTS -190
The DCNTS is a two channel Phase and Amplitude noise analyzer. Its dual demodulator architecture allows the system to use cross-correlation to cancel its internal noise and limitation; it is like comparing the outputs of 2 systems and only display the similarities while rejecting differences. Its main extension is the Residual Noise measurement front-end which includes all necessary hardware to automatically measure residual noise on 2-ports devices either in RF frequencies or microwave. It could be a frequency multiplier or divider, an amplifier or any other phase coherent input to output device.
