MMBX/SMP-MAX

Product catalog summary

Introduction to MMBX:
MMBX connectors are designed for compact applications with board-to-board distances under 7mm, ideal for telecommunication systems. They support frequencies from DC to 12.4 GHz and are compatible with automated assembly processes.

Interface Specifications:
The MMBX interface features slotted and flared designs to meet specific electrical and mechanical standards, with key dimensions provided for compatibility and performance assurance.

Characteristics:
These connectors have a 50Ω impedance and a frequency range up to 12.4 GHz. They offer low VSWR, high insulation resistance, and a dielectric withstanding voltage, with mechanical endurance rated for 100 matings.

Plugs and PCB Receptacles:
Available in various configurations, including straight and right-angle plugs, designed for flexible and semi-rigid cables, with specific part numbers and packaging details.

Adapters:
MMBX adapters come in snap-slide and slide-slide types, with options for different board-to-board distances and between-series configurations.

SMP-MAX Introduction:
SMP-MAX connectors accommodate larger misalignment tolerances, supporting board-to-board distances of at least 2.0 mm and a tilt of 3°, operating up to 6 GHz for broadcast and wireless communications.

General Features:
Both MMBX and SMP-MAX connectors are microminiature coaxial connectors designed for high-density packaging and wireless telecom applications, offering cost-effective solutions with high power handling and mechanical misalignment capabilities.
