SMA(M) TO QMA(F) ADAPTOR 4GHZ

1. Frequency Range:
   • Up to 4 GHz: The adapter is designed to operate efficiently at frequencies up to 4 GHz. Some adapters can handle higher frequencies, so ensure it meets your specific frequency requirements.
2. Impedance:
   • 50 Ohms: Standard impedance for most RF systems, ensuring good signal matching and minimal signal reflection.
3. Connector Types:
   • SMA Male: Features a center pin and is threaded for a secure connection. Designed for high-frequency applications.
   • QMA Female: Features a center socket with a quick-lock mechanism, allowing for a push-pull connection. This type of connector is generally used for quick and secure connections and is similar in function to the SMA connector but with a different coupling method.
4. Insertion Loss:
   • Typically ≤ 0.2 dB: Indicates the loss of signal power as it passes through the adapter. Lower insertion loss values are preferable to maintain signal strength.
5. Return Loss:
   • Typically ≥ 20 dB: Reflects how well the adapter maintains impedance matching. Higher values indicate less reflected signal and better performance.
6. VSWR (Voltage Standing Wave Ratio):
   • Typically ≤ 1.2: Represents how effectively the adapter maintains impedance and minimizes signal reflections. Lower VSWR values indicate better performance.
7. Construction Material:
   • Body: Usually made from high-quality materials such as brass or stainless steel for durability.
   • Plating: Typically gold or nickel-plated to ensure good conductivity and resistance to corrosion.
8. Temperature Range:
   • Typically -55°C to +165°C: Ensures reliable operation in a range of environmental conditions.
9. Size and Weight:
   • Compact Design: Designed to be compact and lightweight for easy integration into RF systems.

Example Part Number:

• Manufacturer: Check with RF component suppliers such as Amphenol, Pasternack, or similar companies.
• Part Number Example: While specific part numbers can vary, you might find something like Pasternack PE4510 or similar. Verify with the exact specifications from the supplier.

Applications:

• RF and Microwave Systems: Used to connect SMA male and QMA female connectors in RF applications.
• Communication Equipment: Useful in systems where quick-lock QMA connections are required.
• Test and Measurement: Commonly used in testing environments where ease of connection and disconnection is beneficial.

Visual Inspection:

• Connector Compatibility: Ensure the connectors are properly matched as SMA male and QMA female, with the correct pin and socket configurations.

When selecting an SMA Male to QMA Female adapter, ensure it meets your frequency, impedance, and performance requirements. Always check the datasheets and specifications from the manufacturer to confirm compatibility and optimal performance for your application.
