SMA F for PCB solder Edge Mount

Description

The SMA Female Edge Mount (End-Launch) Connector is a high-performance RF interface designed to slide onto the edge of a printed circuit board. Unlike through-hole or SMT connectors that sit on top of the board, the edge mount design allows the signal to travel in a straight, horizontal line from the trace to the connector. This coaxial-to-planar transition is critical for maintaining signal integrity at microwave frequencies.

Optimized for High-Speed Signal Integrity

By eliminating the need for vertical transitions (vias), the edge mount SMA significantly reduces parasitic capacitance and inductance. This makes it the industry standard for RF development boards, high-speed digital circuits, and microwave modules. The gold-plated brass body and PTFE insulator ensure a stable 50 Ohm environment for frequencies reaching up to 18 GHz (depending on the PCB substrate).

Key Technical Advantages:

• End-Launch Configuration: Slides onto the PCB edge, sandwiching the board between the ground legs for a balanced, high-strength mechanical connection.

• Superior VSWR Performance: Minimal signal reflection due to the linear signal path, making it ideal for precision testing and measurement equipment.

• Low-Profile Design: Since it sits flush with the board edge, it is perfect for slim enclosures and rack-mounted equipment where vertical clearance is non-existent.

• Broad PCB Compatibility: Designed for standard board thicknesses (typically 1.6mm / 0.062″), with the center pin aligning perfectly with the microstrip or coplanar waveguide trace.

• Premium Materials: High-purity gold plating ensures maximum conductivity and prevents oxidation, even in high-vibration or industrial environments.
