TE Connectivity / Laird External Antennas U.FL/MHF4L to Reverse Polarity SMA Cable Assemblies are engineered for peak performance up to a maximum of 7.5GHz. The 50Ω cable assemblies minimize system losses to within known parameters during operation up to +85°C. The U.FL/MHF4L to Reverse Polarity SMA components offer an omnidirectional pattern type in various cable lengths with a 6000MHz to 7500MHz maximum frequency range.
