Model: KC.CW.00443
The TOXU KC.CW.00443 is a 50 Ω RF1.37 coaxial pigtail for internal RF connections. It connects a matching board receptacle to a soldered antenna feed or RF connection point.
First-Generation I-PEX-Type Plug
The micro coaxial plug connects to a matching receptacle on the host PCB.
Stripped and Tinned Solder End
The exposed center conductor and shield are pre-tinned for soldering.
White RF1.37 Coaxial Cable
The cable has a nominal outer diameter of 1.37 mm and a characteristic impedance of 50 Ω.
226 mm Finished Length
The finished assembly measures 226 ± 1 mm and has a blue identification sleeve marked 23 near the plug.
The TOXU KC.CW.00443 is a single-ended RF coaxial cable assembly made with white 50 Ω RF1.37 cable. One end uses a first-generation I-PEX-type micro coaxial plug. The opposite end has a stripped and tinned center conductor and shield for direct solder termination.
The assembly is intended for OEM equipment designs where the host PCB has a micro coaxial receptacle and the antenna or RF board uses solder pads.
50 Ω RF1.37 Cable
The 1.37 mm outer diameter allows the cable to be routed through compact electronic assemblies.
Micro Coaxial Plug and Solder Termination
The plug mates with a matching board receptacle. The prepared end provides separate connections for the RF signal and ground.
Blue Identification Sleeve
A blue heat-shrink sleeve marked 23 in white identifies the cable near the connector end.

Embedded Antenna Feeds
Connect a board-mounted micro coaxial receptacle to the feed and ground pads of an internal antenna.
OEM RF Interconnects
Route an internal RF connection between a PCB receptacle and a solder termination point in compact equipment.
Host PCB receptacle → RF1.37 coaxial pigtail → Antenna or RF solder pads
Verify the mating receptacle and cable reach before assembly. Solder the tinned center conductor to the RF feed pad and the tinned shield to the designated ground pad according to the host design.
TOXU supplies RF cable assemblies, connectors and embedded antennas. Share your receptacle part number and antenna feed requirements for help reviewing the complete RF connection.
OEM Cable Assembly Support
Discuss connector fit, finished cable length and solder-end preparation for your equipment layout.
TOXU Tech supplies RF cable assemblies, RF connectors and antennas for OEM equipment manufacturers and system integrators.
How is the other end terminated?
The center conductor and shield are stripped and tinned for direct soldering.
What is the finished length?
The finished assembly length is 226 ± 1 mm.
How can I verify the mating receptacle?
Provide the receptacle part number or PCB connector drawing so TOXU can check the mating interface.
