The Samtec IP5-04-05.0-L-S-1-L-TR is a 4-port, 50 Ohm RF plug from the ISORATE® IP5 series, built as a surface-mount female socket with gold-plated copper alloy center contacts. It's designed for controlled-impedance signal paths up to 9.5 GHz, with a 3 dB insertion loss ceiling that sets the attenuation budget for the link.
Why the 9.5 GHz Ceiling and 50 Ohm Impedance Matter
The 9.5 GHz max frequency and 50 Ohm impedance define the usable signal band. Gold center contact plating supports operation up to 125°C.
4-Port vs 2-Port and 8-Port Siblings
The IP5-04-05.0-L-S-1-L-TR sits between the 2-port IP5-02-05.0-L-S-1-TR and the 8-port IP5-08-05.0-L-S-1-TR within the same ISORATE IP5 series. Pick the 4-port when your board needs exactly four coaxial signal paths in one connector footprint; the 2-port saves space for a two-line run, and the 8-port consolidates a denser harness without multiplying connector bodies.
