SQGB1225D 1.2GHz Gain Block

Query


The SQGB1225D 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 1225 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.
