Overview

The QMS-026-05.75-L-D-RF1 is a high-speed mezzanine connector from Samtec's Q Series, designed for high-bandwidth board-to-board applications. This 52-position header features an integrated ground plane and specialized RF plugs to maintain signal integrity in mixed-signal environments. It utilizes a 0.635mm (0.025 inch) pitch and is optimized for surface mount assembly with built-in board guides.

Why Choose This Part

This connector features a dedicated ground bus (plane) that significantly reduces crosstalk and improves EMI performance. The inclusion of two RF plugs within the standard connector footprint allows for high-frequency signal transmission alongside standard digital I/O without requiring separate coaxial cables.

Applications

High-Speed Data Mezzanine
Connecting secondary daughtercards to primary system boards for high-speed differential signal routing.
Mixed-Signal RF Modules
Integrating digital logic and RF signals through a single connector interface using the integrated RF plugs.
Telecommunications Infrastructure
Use in high-density networking hardware where signal integrity and low crosstalk are required across 10mm to 12mm stack heights.

Also Consider

QMS-026-05.75-L-D-A Samtec Inc. - Choose this variant if RF plugs are not required but the same 52-pin digital layout and ground plane are needed.
QSH-030-01-L-D-A Samtec Inc. - A higher density alternative from the Q Strip family for applications requiring more signal pins in a similar footprint without RF capabilities.
