This is one Mini-Circuits used 10-2000MHz 50 Ohm Medium Power RF Amplifier, Model Number: ZFL-2000 with SMA Female Connector. I believe this is non-RoHS. I tested each of the amplifier I have, and see attached plot for typical noise figure, gain and S11, S22 across 10MHz to 2000MHz. I have total 16 units in hand and will provide buyer each unit with test plot (by email once buyer purchase it, all plots are very similar in performance as example attached).
