378A04 -
PCB Piezotronics, Inc.
The 378A04 is a matched system that is comprised of a high sensitivity microphone and a low noise preamplifier that contains a built-in filter that enables the free-field response to remain flat over a wide frequency range. The system requires a minimum of 4 mA and measures to 6.5 dBA (5.5 dBA typical) within a cost efficient, prepolarized (0V) design. PCB's model 378A04, the industry's first prepolarized low noise microphone and preamplifier system allows you to measure extremely low amplitudes. In the past this was only possible with externally polarized solutions. With a typical noise floor of 5.5dBA, this microphone system delivers all of the benefits commonly associated with prepolarized systems.

NS-7001 -
Innovative Technical Systems
The NS-7001 is high-power noise source specifically designed to operate in the 2.11-2.17 GHz UMTS band. It features flat output power that is regulated over a wide temperature range with high rejection outside the operating band of interest. Logic control is provided to enable/disable the noise source and an internal BIT function continuously monitors the output power. Other frequency bands and power levels are available.

Peaceful Thriving Enterprise Co Ltd
Multi-Channel automotive noise finder is a portable equipment to diagnose the defect of the vehicle. When the generator is running, it can detect the impact and vibration due to the defect and failure of bearing, gear, valve, crank, cylinder, gear box, and vehicle body…etc. With this equipment, the repairer can clearly locate which part of the machine cause the noise and how serious is it; even though the repairer operates the equipment in a very noisy environment.

Precision Milimeter Wave
These amplifiers allow methods of communication with distant spacecraft or probe the history and composition of the universe through radio astronomy. It is also used to study basic phenomena through low-temperature physics research as we have seen with the growth in quantum computing. These devices can achieve noise performance that push beyond the limits of classical physics into the quantum realm. Cryogenics LNA’s find use from low frequencies through several hundreds of gigahertz fo ruse in a variety of technologies. Without cryogenic low noise amplifiers, entire branches of experimental science simply would not exist.View more Low Noise Cryogenic Microwave Amplifiers

J2180A -
PICOTEST Corp.
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.
