The R-RF-40 Broadband Microwave Amplifier is a benchtop instrument specifically designed for high-speed lithium niobate electro-optic modulators. It amplifies tiny high-speed signal levels to a higher level than driving the modulator. It goes niobium Lithium (LiNbO3) electro-optical modulator work, and having in the broadband range has a better gain flatness in the broadband range.
