The R-RF-20 Broadband Microwave Amplifier is a benchtop instrument specifically designed for high-speed lithium niobate electro-optic modulators, and it amplifies tiny high-speed signal levels to a higher level that driving the modulator, and then it drives niobium Lithium (LiNbO3) electro-optical modulator work, and having in the broadband range has a better gain flatness in the broadband range.

Rofea's modulator bias controller is specially designed for Mach-Zehnder modulators to ensure a stable operation state in various operating environments. Based on its entirely digitized signal processing method, the controller can provide ultra-stable performance. The controller injects a low frequency, low amplitude dither signal, and a bias voltage into the modulator. It keeps reading the modulator's output and determines the condition of the bias voltage and related error. A
