- Frequency Range:
- Up to 4 GHz: The adapter is rated to handle frequencies up to 4 GHz, which is suitable for many RF applications. Check if the adapter can handle frequencies beyond 4 GHz if needed for your application.
- Impedance:
- 50 Ohms: Standard impedance for most RF systems, ensuring proper signal matching and minimal signal loss.
- Connector Types:
- SMA Female: A connector with a threaded coupling mechanism and a recessed center contact.
- TNC Male RP (Reverse Polarity): TNC connectors have a threaded coupling mechanism and are reverse-polarized with the center pin and socket reversed compared to standard TNC connectors.
- Insertion Loss:
- Typically ≤ 0.2 dB: Represents the loss of signal power as it passes through the adapter. Lower values are better for maintaining signal strength.
- Return Loss:
- Typically ≥ 20 dB: Indicates the quality of impedance matching. Higher values mean less reflected signal and better performance.
- VSWR (Voltage Standing Wave Ratio):
- Typically ≤ 1.2: Reflects the efficiency of the adapter in maintaining impedance and minimizing signal reflections.
- Construction Material:
- Body: Usually made from brass or stainless steel for durability and reliability.
- Plating: Often gold or nickel-plated to ensure good conductivity and corrosion resistance.
- Temperature Range:
- Typically -55°C to +165°C: Ensures the adapter operates reliably in various environmental conditions.
- Size and Weight:
- Compact and Lightweight: Designed to be small and easy to integrate into RF systems.
Example Part Number:
- Manufacturer: Check with RF component manufacturers such as Amphenol, Pasternack, or similar suppliers.
- Part Number Example: While specific part numbers can vary, you might find parts like Pasternack PE3797, though it is essential to verify the exact part number based on your requirements.
Applications:
- Wireless Communication Systems: Useful for linking components with SMA and TNC RP connectors.
- RF Test Equipment: Commonly used in lab setups and testing equipment.
- Antenna Systems: For connecting antennas that use TNC RP connectors to devices with SMA connectors.
Visual Inspection:
- Connector Compatibility: Ensure the TNC connector is Reverse Polarity (RP) as indicated by the reversed center pin and socket compared to a standard TNC connector.
When selecting an SMA Female to TNC Male RP adapter, make sure it meets your frequency, impedance, and performance requirements. Always check the datasheets provided by the manufacturer for the most accurate and detailed specifications.
