50 Ohm MCX Receptacle — 6 GHz Signal Path, Now Obsolete
The 1330126-1: It handles signals up to 6 GHz with a rated insertion loss of just 0.1 dB, making it a clean RF interconnect for applications like GPS modules, wireless test equipment, or compact RF front-ends where the snap-on MCX coupling saves board space over an SMA.
What the 50 Ohm and 6 GHz Ratings Mean for Your RF Path
The 6 GHz ceiling covers common bands like 5 GHz Wi-Fi, ISM, and cellular up to mid-band 5G, but not mmWave. The 0.1 dB insertion loss at frequency is tight; you can budget for it without recalculating your link margin.
Obsolete — Sourcing the 1330126-1 or Finding a Cross
No official successor part number appears. For a BOM line that still calls out this exact MCX receptacle, the sourcing path is surplus and broker channels — verified date-coded stock from independent distributors, quoted per RFQ with no franchise lead time.
