Introduction

The J2180A and J2180A-20 low noise preamplifiers provide 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 (J2180A), 20Hz to 100MHz (J2180A-20) and 10Hz to 1MHz (J2181A), the preamplifiers improve the sensitivity of oscilloscopes, network analyzers and spectrum analyzers while reducing the effective noise floor and spurious response. The J2180A-20 is lower noise than the J2180A at the cost of some low frequency bandwidth. The preamplifiers can also serve as a low frequency DC blocker for a spectrum analyzer or you can use them to connect a high input impedance oscilloscope probe to 50 Ohm equipment.
