- Frequency Range:
- Up to 4 GHz: The adapter is rated to operate efficiently at frequencies up to 4 GHz. Many adapters can handle higher frequencies, so check if you need a higher frequency rating.
- Impedance:
- 50 Ohms: Standard impedance for most RF systems, ensuring good signal matching and minimal signal reflection.
- Connector Types:
- SMA Male RP: Features a center pin and is designed to mate with an SMA female RP connector.
- SMA Female RP: Features a center socket and is designed to mate with an SMA male RP connector.
- Insertion Loss:
- Typically ≤ 0.2 dB: Indicates the loss of signal power as it passes through the adapter. Lower values are preferable for maintaining signal strength.
- Return Loss:
- Typically ≥ 20 dB: Reflects the quality of impedance matching; higher values indicate less reflected signal and better performance.
- VSWR (Voltage Standing Wave Ratio):
- Typically ≤ 1.2: Indicates how efficiently the adapter maintains impedance and minimizes signal reflections.
- Construction Material:
- Body: Usually made from brass or stainless steel for durability.
- Plating: Typically 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 wide range of temperatures.
- Size and Weight:
- Compact Design: Generally designed to be compact and lightweight for ease of integration into RF systems.
Example Part Number:
- Manufacturer: Common manufacturers include Amphenol, Pasternack, and similar RF component suppliers.
- Part Number Example: A part number such as Pasternack PE3796 might be relevant, but always verify with the exact specifications and part number from the supplier.
Applications:
- Wireless Communication Systems: Connecting devices that use RP SMA connectors.
- RF Test Equipment: Useful in setups where reverse polarity SMA connections are standard.
- Antenna Systems: For linking antennas with RP SMA connectors to other components.
Visual Inspection:
- Connector Compatibility: Ensure that both connectors are truly Reverse Polarity SMA, characterized by the reversed center pin and socket compared to standard SMA connectors.
When selecting an SMA Male RP to SMA Female RP adapter, ensure it meets your frequency, impedance, and performance requirements. Always refer to the manufacturer’s datasheets and product specifications to confirm that the adapter is suitable for your specific application.
