U.FL to N Cables

U.FL to N-type Connector Antenna Cables

U.FL antenna cables connect antennae to U.FL jacks on mounted on PCB boards. The combination of N-type connectors with U.FL create a convenient adapter cable to connect a medium or large-sized external antenna to a PCB.  These cables are often used for a broad range of Internet of Things (IOT) applications where they used to for longer-range wireless to connect to a LAN or other source of internet connectivity.

All of our U.FL to N antenna cables are impedance-matched to 50 Ohms, which is the standard for WiFi and almost all typical wireless applications, including Bluetooth, LTE (4G), GSM(3G), ZigBee, and LoRa.  Our antenna cables consistently low broadband VSWR have made them popular over the years in all of these applications. 

The three types of coax that we use for U.FL cables are all impedance match to 50 Ohms:

We typically make U.FL to N cables with 1.13mm coax, which is a very thin and flexible cable, with a black jacket.  While 1.13 coax is not the low-loss option, it is often very important to use this very thin and flexible coax for two reasons:

  1. In tight spaces (inside of cases and enclosures), such a thin coax is often necessary.  Sometimes limited size of ports, requires the use of 1.13 coax.
  2. 1.13 enables the U.FL connector to snap down securely on the jack without popping off (as will sometimes happen with RG174, unless you glue the connector to the jack).  

We can make special orders of U.FL cables with 1.32mm coax or RG174 (both of which are lower signal loss options) or 1.13mm cable, for better flexibility.  1.32mm is very thin and flexible, like 1.13 coax.

All three of these coaxial cable types have a central wire (insulated by plastic) to conduct the RF signal, further surrounded by a braided mesh, shielding the conducting wire from electromagnetic interference. The double-shielded 1.32mm also includes a second , outer insulating layer that covers the conducting shield. The dbouble-shielded design provides extremely efficient data transmission and where appropriately connected to an antenna the RF signal can be transmitted with minimal signal loss.

The U.FL female right-angle connector mates with U.FL jack/cable-connector U.FL-LP-66, found on Bluetooth devices, ZigBee / XBee radios, and mini-PCI wireless cards.  

Our U.FL connectors are precision machined and gold-plated for low loss.

The U.FL to N-type connector cable is particularly useful for connecting an external antenna to a wireless card or board. It grants the utility of the N-type connector, a mid-sized threaded connector able to carry microwave signals to the far smaller U.FL connector, an Ultra-Minature coax connector (UMCC), typically embedded in mini-PCI wireless cards. This enables the connection of larger and powerful antennae, which typically possess an N-type connector, to a Wi-Fi set-up via the U.FL connection.
