Ultra Low Noise Preamp
J2180A
-
The J2180A low noise preamplifier provides a fixed, AC coupled 20dB gain while converting a 1 MOhm input impedance to a 50 Ohm output impedance. With a 3dB bandwidth of 0.1Hz to 100MHz, the preamplifier improves the sensitivity of oscilloscopes, network analyzers and spectrum analyzers while reducing the effective noise floor and spurious response. The preamplifier can also serve as a low frequency DC blocker for a spectrum analyzer or you can use it to connect a high input impedance oscilloscope probe to 50 Ohm equipment.

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.

Low Noise Pre-Amplifiers
-
Low Noise Pre-Amplifier and companion external low noise amplifier (LNA) are used to amplify low level microwave signals. The Pre-Amplifier contains an AC/DC power supply, internal low noise amplifier, and a bias tee to source a DC bias voltage on the RF input connector.To overcome cable loss between the test antenna and the Pre-Amplifier assembly, a remote low noise amplifier (LNA) is mounted directly onto the 10 GHz antenna. A bias tee inside the Pre-Amplifier chassis powers the remote LNA through the coax cable interconnecting the pre-amplifier and the 10 GHz test antenna.
