Description
SMA Male Plug to SMA Female Jack LMR240 10 meter cable with Jye Bao Connectors.
LMR240 is a type of coaxial cable that is commonly used in various applications, including telecommunications, broadcasting, and RF (radio frequency) systems. Here are some key characteristics and information about LMR240 coaxial cable:
- Construction: LMR240 cable consists of several layers. The innermost conductor is typically made of solid copper or copper-clad steel, providing the electrical signal transmission path. It is surrounded by a dielectric insulating layer, which is usually made of foam polyethylene. The outer conductor is a braided shield made of tinned copper, providing shielding against electromagnetic interference (EMI). Finally, there is an outer jacket made of durable and weather-resistant material such as PVC (polyvinyl chloride) or polyethylene.
- Impedance: LMR240 has an impedance of 50 ohms. This impedance value ensures optimal signal transfer in applications where impedance matching is crucial, such as in RF systems and high-frequency data transmission.
- Attenuation: Attenuation refers to the loss of signal strength over the length of the cable. LMR240 has relatively low attenuation, allowing it to transmit signals over longer distances without significant degradation. The attenuation characteristics depend on the frequency range, but as a general guideline, LMR240 offers low loss up to around 3 GHz.
- Diameter and Flexibility: LMR240 has a moderate diameter, typically around 6.1 mm (0.24 inches), which makes it relatively flexible and easy to handle compared to thicker and stiffer cables. This flexibility facilitates installation and routing in tight spaces.
- Power handling: LMR240 is designed to handle moderate power levels commonly encountered in telecommunications and RF applications. However, if you have specific power requirements, it is important to consult the manufacturer’s specifications or seek expert advice to ensure the cable can handle the intended power levels.
- Connector Compatibility: LMR240 cables typically use connectors with an impedance of 50 ohms, such as Type N, BNC, or SMA connectors. The choice of connector depends on the specific application and equipment being used.
- Environmental Durability: LMR240 cables are designed to withstand harsh environmental conditions. The outer jacket provides protection against moisture, UV radiation, and other environmental factors, making it suitable for both indoor and outdoor applications.
LMR240 is just one variant within the LMR series of coaxial cables, each offering different characteristics and performance specifications. It is always recommended to consult the manufacturer’s datasheet or seek expert advice from RFShop Australia for precise details about the specific variant and its suitability for your application.
