IPEX MHF2 Mini Coax Connector

IPEX MHF2 Mini Coax Connector


IPEX MHF2 (MHFII) is the generation 2 of IPEX micro RF coaxial connector. It’s mating height (2.0mm) is lower than IPEX MHF (2.5mm). The frequency is up to 6GHz and can be used widely for application of GPS antenna and GPS modules, GSM antenna and GSM modules, WLAN cables and WLAN modules.

IPEX (IPX) MHF2 connector is compatible to Hirose U.FL-LP(V)-040 series, and Sunridge MCB2/ MCBG2 series. Having same working performance, but IPEX/IPX RF connector has great advantage in cost and delivery. You can get IPEX 20311-011R coaxial cable and MHFII 20279-001E-01 receptacle connector in 7 days from Wellshow!
