In general, the common applications of 50 ohm coaxial cables include but are not limited to:
- Antennas, Wi-Fi, Cellular, and GPS
- RF Test and Measurement Equipment
- Telecom, Base Stations, and Distributed Antenna Systems
- Automotive RF Systems
- Aerospace, Defense, and Radar
- Industrial, Robotics, IoT, and Medical Equipment
In applications where standard cable lengths, connector combinations, or performance levels are not suitable, custom RF cable assemblies may be used to meet specific system requirements.
Antennas, Wi-Fi, Cellular, and GPS
One of the most common uses of 50 ohm coaxial cable is connecting RF modules to antennas. Wi-Fi routers, access points, cellular modems, radios, IoT gateways, and GPS/GNSS receivers all rely on controlled-impedance transmission paths to carry high-frequency signals with minimal reflection and loss.
In these applications, the cable assembly may connect a transmitter, receiver, or transceiver to an external or embedded antenna.
Frequently Asked Questions
What is the difference between Cavity and LC filters? +
LC filters use discrete inductors and capacitors, making them smaller and cheaper, but they suffer from higher insertion loss and lower power handling compared to Cavity filters.
