J2116A Power Amplifier & High CMRR Isolation Amplifier
Description
The J2116A is a combined unit with source power amplifier and ground isolator with up to 22.5dB gain and 100dB CMRR. It is used to improve signal-noise in crosstalk and ultra-low impedance measurements. It achieves +20dBm output with +/-9V power and +22.5dBm with +/-12V power. It works with all popular VNAs including the Keysight E5061B and the OMICRON Lab Bode 500.
The J2116A can be powered from +/-9V – +/-12V using an external power supply or batteries. Power is applied to the unit using connections from a supplied 4-pin Molex connector VEE-GND-GND-VCC (left to right). This is so that an external power supply can be used to power the isolator. SMA connectors are provided to input and output connections.

Ground Loops What They Are, Why We Care, and How to Fix Them
Power rail noise is one of the most significant sources of jitter in high-speed systems, phase noise in RF systems, and noise in A/D and D/A converters. Semiconductor manufacturers are responding by continuously improving Power Supply Rejection Ratio (PSRR).
