- Frequency Range:
- Up to 4 GHz: The adapter is designed to operate effectively at frequencies up to 4 GHz. Ensure it meets your application requirements, as UHF connectors are traditionally used for lower frequencies.
- Impedance:
- 50 Ohms: The standard impedance for most RF systems, ensuring proper signal matching and minimal signal reflection.
- Connector Types:
- SMA Female: Features a center socket and threaded coupling mechanism. SMA connectors are designed for higher frequency applications and have a small form factor.
- UHF Female: Features a center socket with a larger diameter compared to SMA connectors. UHF connectors are known for their durability but are generally used for lower frequencies.
- Insertion Loss:
- Typically ≤ 0.3 dB: Indicates the loss of signal power as it passes through the adapter. Lower insertion loss is preferred to maintain signal strength.
- Return Loss:
- Typically ≥ 15 dB: Reflects how well the adapter maintains impedance matching. Higher values indicate less signal reflection and better performance.
- VSWR (Voltage Standing Wave Ratio):
- Typically ≤ 1.5: Represents how effectively the adapter maintains impedance and minimizes signal reflections. Lower VSWR values indicate better performance.
- Construction Material:
- Body: Usually made from brass or stainless steel for durability.
- Plating: Often gold or nickel-plated to ensure good conductivity and resistance to corrosion.
- Temperature Range:
- Typically -55°C to +165°C: Ensures reliable operation across a range of environmental conditions.
- Size and Weight:
- Compact Design: Designed to be compact and lightweight for ease of integration into RF systems.
Example Part Number:
- Manufacturer: Look for RF component suppliers such as Amphenol, Pasternack, or similar companies.
- Part Number Example: For specific part numbers, you might find something like Pasternack PE4557 or similar models. Always verify with the exact specifications from the supplier.
Applications:
- RF and Microwave Systems: Used to connect components with SMA female and UHF female connectors.
- Communication Equipment: Useful for systems where these different connector types need to be integrated.
- Test and Measurement: Common in RF testing environments where different connector types are needed.
Visual Inspection:
- Connector Compatibility: Ensure that both connectors are properly matched as SMA female and UHF female, with appropriate pin and socket configurations.
When selecting an SMA Female to UHF Female adapter, ensure it meets the frequency, impedance, and performance requirements for your application. Always refer to datasheets and specifications provided by the manufacturer to confirm compatibility and optimal performance.
