RF Cable Assemblies

Custom RF Flexible cable assemblies

RF cable assemblies are finished cables with connectors on both ends. These are sometimes referred to as an RF cable harness. Custom RF Flexible cable assemblies offer exceptional flexibility, bending smoothly to fit tight spaces while ensuring reliable RF signal transmission. These cables carry radio and microwave signals between devices. Examples include radios, antennas, and lab equipment. Each cable is built to order. You decide the cable type, length, and connectors. Some systems need very flexible cables, while others need standard or rugged cables. RF flexible cable assemblies provide exceptional bending and routing capabilities in compact electronic devices, they can be made for outdoor use or for tight spaces inside machines. By selecting the appropriate conductor and insulation, we ensure the signal remains strong and stable. Every cable is thoroughly tested before shipping to ensure it functions correctly.

RF Cable assemblies types

RF cable assemblies come in different types to fit different signal needs and work settings. Each type uses the right connectors and cable design to keep signals clear and steady. Using the right assembly helps stop signal loss and reduces noise. This makes systems safer, faster, and more reliable over time.

Panel mounted RF connector

Panel-mounted RF connectors are fixed to a device or a metal panel. You can connect and remove cables from the outside. Common types include N-type, TNC, and BNC connectors. These connectors hold the cable steady and protect the connection. They are often used on antennas, test equipment, and racks. Engineered for low insertion loss and reliable impedance matching, they feature rugged construction with IP-rated sealing to resist dust, moisture, and vibration in harsh industrial or outdoor settings. Panel-mounted connectors make it easy to replace cables without opening the equipment, supporting high-frequency signals for critical communications, automation, and medical device applications.

Fakra Connectors

Fakra connectors are special RF connectors used in cars. They are common in cameras, GPS systems, and car radios. Each Fakra connector has a unique color and shape. This makes it hard to plug in the wrong cable. These connectors lock firmly in place and resist vibration, heat, and moisture. Due to this, they are highly reliable in moving vehicles. We build Fakra cable assemblies that meet automotive standards, ensuring stable signal transmission while driving.

Water proof SMA

Waterproof SMA connectors are designed for use in outdoor or wet environments. They use rubber seals or O-rings to block water and dust. Many are rated IP67 or IP68, which means they can handle rain or splashes. These connectors are used in outdoor radios, cellular equipment, and industrial sensors. They offer the same signal quality as standard SMA connectors but with extra protection. This helps keep systems functioning in harsh weather conditions.

N type / BNC to SMA

Some systems use different connector types. We make hybrid cables that connect one type to another. For example, an N-type to SMA cable connects a large connector to a smaller one. BNC-to-SMA cables are commonly used in labs, where test equipment interfaces with small RF boards. These cables are tested to ensure the signal remains clean. Hybrid wires make it easy to connect different devices without requiring changes to your setup.

RF cable assemblies cable and connector

The cables and connections that go into our RF cable assemblies are very good. A central conductor in each cable carries the signal. There is a metal barrier and insulation around it that stops interference. An outer jacket protects the cable from damage. A lot of thought went into choosing each cable part to make sure it lasted as long as possible and didn't lose any signal. This makes the cable good for both indoor and outdoor use.

Bare or Silver plated conductors

Most of the time, copper is used for the inner conductor in coaxial cables. Many people use bare copper because it lets signals flow freely. Copper that has been silver-plated is often used in cables that work better. It makes soldering easier and improves the quality of the signal. The outer shield is also made of copper, which is sometimes plated to keep it from rusting. With the right conductors, it is possible to keep a strong signal, even at high frequencies.

Teflon or PA insulator

The insulation inside the cable is what keeps the signal steady. PTFE (Teflon) is a very good insulator that loses very little signal. It will stick no matter how hot or cold it gets. Some cables use polyethylene (PE) and polyamide (PA). These materials cost less than Teflon, but they don't work as well. Teflon is great for important messages. For less complicated uses, PA or PE is enough.

RF adapters

You don't need a whole cable with RF adapters because they let you connect two different types of connectors. For example, you can connect a SMA connector to an N-type jack with an SMA-to-N adapter. System adapters make it easier to set up and give systems more options. We use precision parts to cut down on the small amount of signal loss that each adapter causes.

N Type coaxial connector

The N-type connector is an RF connection that is both strong and threaded. It can handle a lot of power because it has a 50-ohm design. It also works well outside. Base stations and antennas often use N-type connections. They work better at high frequencies than other types of connections. This is why they can be used in outdoor and harsh RF systems.

LMR 200/400/600 cables

LMR cables are long-male RF (low-loss) coaxial cables. You can choose from a number of different sizes. LMR-200 is thin and flexible at the same time. People often use RG-58 instead. LMR-400 is thicker and loses less signal. It is often used in antennas and base stations. LMR-600 is very thick and has the least amount of loss. It is used in systems with long cable runs or high power.

Custom Coaxial connector & Cables

SMA connectors

Small RF connections called SMAs send high-frequency signals. Because they work with 50-ohm systems, they are often used in small RF modules, test instruments, and WiFi devices. SMA connections are easier to get a steady signal from because they screw on tightly. The female SMA has an opening in the middle, while the male SMA has a central pin. Their small size is a plus when space is limited. We make SMA cable assemblies out of standard cables like RG-316 and LMR-style cables. We now offer the reverse-polarity SMA (RP-SMA) connections that are often used in wireless devices for your convenience. You can choose between straight and right-angle.

RP or male and female

Reverse-polarity (RP) connections can be either male or female, and they look like regular connectors on the outside. But the central pin is actually pointing in the other direction. For example, an RP-SMA male has a hole in the middle instead of a pin. These connections are often used to make sure that WiFi devices work. The cable will work with your system as long as you choose the right RP or standard connections. We have both standard and RP versions of most connections, such as SMA, SMB, and MCX. When selecting connectors, verify device interface specifications to ensure signal integrity and prevent mating with incompatible ports.

Fakra various codes

Fakra connections are used in a lot of cars. They come in many different shapes and colors, so you can't plug in the wrong one by mistake. Each color sends a different message. Black, blue, green, violet, and white are the most common colors for AM/FM radio Fakra connections. For GPS, keyless entry, cellular signals, and satellite radio, the colors are black, blue, green, violet, and white. We can make Fakra cable assemblies to your exact specifications, such as the color code, style (straight or right angle), and type of connection (male or female). Our products have undergone rigorous testing to ensure reliable connectivity for vehicles in harsh environments.

Built for Tough Conditions

Heat

Our RF cable assemblies can handle very hot and other tough situations. Their signals stay clear and steady even when the temperature changes suddenly or when it's very hot or cold. We use PTFE and other strong insulating materials to make sure the cables stay in place and work well for a long time. This is one way that machines can keep working well and accurately.

Motion

Every cable goes through a lot of testing to make sure it won't crack when it's bent, shaken, tugged, or moved. These kinds of cables are best for machines that need flexible cables, places with a lot of movement, or both. The wire doesn't get damaged even when machines run all the time because its inner layers are so strong. This outer jacket has sealed connectors and shielding to keep out dust, noise, water, and the elements.

Tough Conditions

We use materials that don't rust and strong connections to make the cables last longer in tough conditions. Because of this, these cables are used in cars, planes, and machines that make things. These RF cable assemblies are made to last in both normal and extreme conditions. This helps systems run smoothly, cuts down on the need for repairs, and stops problems from happening.
