SQ Cable Device

The BGS8618/20/22/25/27D is a Hybrid Power Doubler gain block. It is optimized for exceptionally low distortion and low noise figure in a 75 Ω power doubler amplifier circuit. It provides excellent input and output return loss over the 45 to 860 MHz CATV HFC infrastructure.

The device is ideally suited for use in CATV applications where low distortion and high output power are required.

The device package is complied with standard SOT-115J.
