The Cause and Eliminate Method of Self-excited Oscillation in Long Cable Amplifier Circuits

SMA long cable distributed capacitance is easy to trigger broadband amplifier circuit’s self-oscillation. In this study we design an amplifier circuit based on OPA691 chip, discuss the influence of long cable’s distributed capacitance, then prompt a solution to add 50Ω compensation resistor between...
