Dear sir:
I got oscillation issue on THS4271. The circuit schematic is as attached. The input is differential sine wave on positive and negative terminals with 10k differential resistor. The output oscillates at 300Mhz or mixed frequency as attached. Once turn off the sine wave SG, the output continue to oscillate. If changing THS3091 with appropriate recommended Rf, the circuit is clean without oscillation. Could someone tell me what's going on with THS4271?
Thanks!
Brian
