Product details

75 Ohm MCX Jack for Board-Edge RF

The board-edge, cutout-mount SMT footprint places the connector at the PCB periphery, keeping the RF trace short to the launch point.

RF Performance and Construction

The 0.1 dB insertion loss across the 6 GHz band is a tight spec for a snap-on subminiature connector — it tells you the interface is well-matched and the centre contact alignment is consistent. Shield termination and contact termination are both solder, meaning the jack is soldered directly to the board — no crimp, no compression.

Frequently asked questions

What is the insertion loss of Amphenol 252151-75?

The insertion loss is 0.1 dB across the rated frequency range up to 6 GHz. This is a typical spec for a well-matched MCX interface at these frequencies.
