IPEX MHF Mini Coax Connector

IPEX MHF Mini Coax Connector


IPEX (IPX) MHF Connector is equivalent of Hirose U.FL connector. IPEX MHF is the generation one of IPEX micro RF coaxial connector. MHF connector is designed to have 2.5mm mating height and can operate 0~6GHz frequency. IPEX MHF can be terminated with 1.13mm and 1.32mm coax cable. IPEX with 1.13mm cable is compatible to Hirose U.FL-LP-068, and IPEX with 1.32mm cable is compatible to Hirose U.FL-LP-066.

IPEX MHF 20279-001E-01 receptacle is commonly designed into GPS modules, GSM modules, WLAN modules. The IPX MHF cable works to adaptor module and antenna.

Having same working performance, but IPEX RF connector has great advantage in cost and delivery. You can get IPEX coaxial cable assembly and Receptacle  in 7 days from Wellshow!
