Smiths Interconnect — Florida RF

SMS-200-48.0-SMS

A: This cable assembly is designed for RF and microwave applications, offering consistent 50 Ohm impedance to ensure signal integrity. Its key technical specifications are: Cable Type: Lab-Flex 200, a flexible and low-loss RF cable. Length: 48.0 inches (1219.2 mm). Maximum Frequency: Up to 18 GHz, suitable for S-band and X-band frequencies. Impedance: 50 Ohms nominal. Outer Diameter: 0.195 inches (approx. 4.95 mm), providing a balance between flexibility and shielding. Connector Type: SMA Male to SMA Male (Straight) connectors.

A: The assembly uses standard SMA (SubMiniature version A) male connectors on both ends. SMA connectors are widely used in RF systems and provide a threaded coupling interface for secure and repeatable connections. The 50 Ohm characteristic impedance of the assembly is a standard industry value, ensuring proper power transfer and minimal signal reflection when connected to other 50 Ohm RF components like amplifiers, antennas, splitters, and test equipment.

A: The assembly is built around the Lab-Flex 200 cable, a low-loss, flexible RF cable. Key benefits include: Low Insertion Loss: Minimizes signal power degradation, which is critical for high-frequency and long-run applications. Excellent Shielding: Protects the transmitted signal from external electromagnetic interference (EMI). Phase Stability: Provides stable electrical length over a range of temperatures and when the cable is flexed, important for phased-array antennas and test setups. Mechanical Durability: Designed to withstand repeated flexing and harsh environmental conditions.

A: Due to its high performance, this cable assembly is used in demanding RF and microwave applications, including: Test and Measurement: Connecting equipment like vector network analyzers (VNAs) and spectrum analyzers to devices under test (DUTs). Aerospace and Defense: Used in radar systems, electronic warfare (EW) suites, and communication links onboard aircraft and ships. Telecommunications: In base stations and satellite communication ground terminals. High-Speed Digital Systems: Where coaxial cables are used for low-jitter clock distribution. ⚠️ Important Sourcing and Datasheet Information: The SMS-200-48.0-SMS is a specialized RF component primarily available through electronics distributors like RFMW. There is no publicly available manufacturer's datasheet for this specific assembly in typical search databases. However, you can visit the Florida RF Labs website and look for information on their "Lab-Flex 200" product series, which details the performance of the cable itself. Distributor websites also provide summary specifications. For new designs or large-volume purchases, it is strongly recommended to request an official drawing from your authorized distributor, as custom lengths and connector options are available.
