TRS278-122-75+ 詳細描述
Product Overview
TRS278-122-75+ is a Mini-Circuits 75 Ω 1:2.78 balanced core-and-wire RF transformer specified for 40 MHz to 1.25 GHz. The unusual 1:2.78 ratio is designed for a specific higher-impedance differential load rather than a conventional 1:2 matching point.
Its 40 MHz to 1.25 GHz band aligns with DOCSIS 3.1 and broadband distribution systems that must cover both return and forward paths. Because the ratio is non-standard, replacement approval must preserve the winding relationship as well as the 75 Ω characterization.

Quality & Sourcing
Antrex Electronics can support sourcing of TRS278-122-75+ 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.
