The J2181A is a low noise preamplifier that provides a fixed, AC-coupled 60dB gain while converting a 1 MOhm input impedance to a 50 Ohm output impedance. With a 3dB bandwidth of 10Hz to 1MHz, the preamplifier improves the sensitivity of oscilloscopes, network analyzers, and spectrum analyzers, while reducing the effective noise floor and spurious response. The J2181A includes wrap-around high permeability shielding to reduce susceptibility to ambient noise. The preamplifier also serves as a low frequency DC blocker (6.3V) for a spectrum analyzer or you can use it to connect a high-input impedance oscilloscope probe to 50 Ohm equipment.
The J2181A preamplifier offers very low noise, fast 100V/uS slew rate for ultra-low noise measurement for PLL, LNA, ADC power rails, and ultra-low noise voltage references and regulators, using an oscilloscope or spectrum analyzer. A typical noise plot shows the noise is 1.5nV/rt_Hz.
