U.FL IPEX MHF Cable Assembly: Types, Specifications, and Applications
Introduction
Modern wireless devices demand compact, lightweight, and high-performance RF connectors. This requirement has led to the widespread use of micro-coaxial RF connectors such as U.FL, UMCC, IPEX, and MHF in antenna cable assemblies. These connectors are specifically designed for space-constrained RF modules while maintaining reliable signal integrity.
This blog explains what these connectors are, how cable assemblies are built, their technical specifications, and where they are used in real-world applications.
What Are U.FL, UMCC, IPEX, and MHF Connectors?
These are microscopic snap-on RF connectors intended for internal antenna connections in small electrical devices.
U.FL - Developed by Hirose
UMCC - Murata equivalent.
IPEX / MHF are industry-standard variations frequently utilized by module makers.
Although their names differ, these connectors are physically and electrically compatible when intended for the same MHF series.
Understanding U.FL and IPEX cable assemblies.
A U.FL cable assembly is comprised of:
A tiny RF connectors on one end (U.FL, IPEX, or MHF)
A coaxial RF wire.
Another RF connectors or antenna termination at the other end
These assemblies serve as a key connector between RF modules and antennas.
Cable Types Used in UFL Assembly
The performance of a cable assembly is strongly dependent on the coaxial cable utilized.
Common Cable Types
RF1.13: ultra-thin, lightweight, short-range usage
RF1.37 - Better shielding, increased endurance
