Z7550-FFNM+

Product Overview

Z7550-FFNM+ is a Mini-Circuits connectorized 50 Ω-to-75 Ω matching transformer specified for DC to 2.3 GHz. This module performs broadband impedance matching between 50 Ω and 75 Ω systems without requiring a PCB-mounted transformer.

Its DC-passing response and 2.3 GHz upper limit suit laboratory setups, CATV interfaces and mixed-impedance RF equipment. The FFNM connector arrangement identifies the exact in-line mechanical interface and should be checked separately from the SMA-equipped FFSF version.

Quality & Sourcing

Antrex Electronics can support sourcing of Z7550-FFNM+ 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.
