When designing RF and wireless systems, engineers often look for reliable SMA PCB connectors that balance performance, availability, and cost. TE Connectivity’s  5-1814400-1  is a widely used right-angle SMA jack for PCB mounting in commercial RF applications. However, its relatively high unit price can significantly increase BOM costs, especially in volume production. Kinghelm  KH-SMA-K513-G  offers a  functionally equivalent and cost-effective alternative , delivering comparable—or even enhanced—RF performance at a fraction of the cost.   Overview of TE 5-1814400-1 The TE 5-1814400-1 is a  right-angle SMA female (jack) PCB connector  designed for cable-to-board RF connections. Its typical applications include RF modules, communication equipment, and commercial wireless devices. Key specifications: l  Interface: SMA, Jack l  Mounting style: PCB Right Angle, Through-Hole l  Characteristic impedance: 50 Ω l  Frequency range: DC–...

As electronic devices continue to shrink while offering more functionality, efficient PCB interconnection has become a critical design challenge.  Board-to-Board connectors  provide a reliable solution for directly connecting two printed circuit boards without using cables, helping designers save space, simplify assembly, and improve signal integrity. In this article, we explore the main types of board-to-board connectors, their applications, key design considerations, and how to select the right solution for your project. 1.  Introduction to Board-to-Board Connectors   A  Board-to-Board connector  is designed to electrically and mechanically connect two PCBs together. Unlike wire-based connections, these connectors enable direct board-level interconnection, making them ideal for compact, modular, and high-density electronic designs. They are widely used in consumer electronics, industrial systems, automotive electronics, and communication equipment, where ...
