Product description

Why weldless end launch connector?

RF coaxial connectors, especially microwave and millimeter wave coaxial connectors are flourishing in high-speed digital and precision sensing applications, and Nowadays highly compact and interconnected microwave and millimeter wave systems call for interconnection between printed circuit boards (PCBs) with minimal losses and mechanical strength.

There are various solutions such as soldered coaxial interconnects for PCBs, as well as custom RF connector harnesses and pins.

While weldless end launch connectors are solder-free and It is retained through mechanical method. The outer conductor is screw-locked, which excels over conventional connectors: it deletes soldering failures ruining  the entire PCB board and  reduces cost by repeated usage.


High-performance End Launch connectors features low VSWR, quick response for single layer or multilayer PCBs where high-frequency signals are transmitted on top layers.

The frequency is available from DC to 110 GHz (1.0 mm coaxial connector), DC to 67 GHz (1.85 mm coaxial connector), DC to 50 GHz (2.4 mm coaxial connector) and DC to 40 GHz (2.92 mm coaxial connector).
