Z7550-FFSF+

Product Overview

Z7550-FFSF+ is a Mini-Circuits connectorized 50 Ω-to-75 Ω matching transformer specified for DC to 2.5 GHz. It converts between 50 Ω and 75 Ω coaxial environments in a ready-to-use connectorized module.

The DC-to-2.5 GHz bandwidth covers CATV, broadband receiver, test and measurement applications without an external matching network. The FFSF ordering code defines the SMA/F connector combination; this mechanical arrangement differentiates it from Z7550-FFNM+.

Quality & Sourcing

Antrex Electronics can support sourcing of Z7550-FFSF+ for production, repair and shortage requirements. Incoming inspection should compare the exact ordering code, operating band, impedance relationship, package or connector configuration and any center-tap or suffix-specific mechanical details. Parts from the same transformer family may not be interchangeable when the ratio, port impedance, lead style or installed geometry changes.
