- Frequency Range:
- Up to 4 GHz: The adapter is designed to operate efficiently at frequencies up to 4 GHz. Many adapters can handle higher frequencies, so always check the exact rating if your application demands it.
- Impedance:
- 50 Ohms: This is the standard impedance for most RF applications, ensuring proper matching and minimal signal reflection.
- Connector Types:
- SMA Male RP (Reverse Polarity): Both ends of the adapter have an SMA male RP connector. In RP connectors, the center pin and socket are reversed compared to standard SMA connectors. This ensures compatibility with RP SMA devices and prevents connection with standard SMA connectors.
- Insertion Loss:
- Typically ≤ 0.2 dB: Indicates the loss of signal power through the adapter. A lower value signifies better performance.
- Return Loss:
- Typically ≥ 20 dB: Measures how well the adapter maintains impedance matching, with higher values indicating better performance.
- VSWR (Voltage Standing Wave Ratio):
- Typically ≤ 1.2: Represents how efficiently the adapter maintains impedance and minimizes signal reflections.
- Construction Material:
- Body: Often made from high-quality materials like brass or stainless steel.
- Plating: Usually gold or nickel-plated for good conductivity and corrosion resistance.
- Temperature Range:
- Typically -55°C to +165°C: Ensures reliable operation across a wide range of temperatures.
- Size and Weight:
- Compact Design: Dimensions and weight are typically designed to be compact for ease of integration.
Example Part Number:
- Manufacturer: Common manufacturers include Amphenol, Pasternack, and other RF component suppliers.
- Part Number Example: For specific part numbers, check with manufacturers or distributors for available models. For instance, Pasternack might have a part like PE3797 (this is a generic example; verify with actual product listings).
Applications:
- Wireless Communications: Often used in systems that require RP SMA connections to avoid mismatches with standard SMA connectors.
- RF Testing: Useful in test setups where RP SMA connections are standard.
- Antenna Systems: For connecting antennas and other RF components with RP SMA connectors.
Visual Inspection:
- Connector Orientation: Ensure that the connectors are truly Reverse Polarity SMA. The center pin on RP connectors is recessed compared to standard SMA connectors.
When selecting an SMA Male RP to SMA Male RP adapter, ensure that it meets the frequency, impedance, and performance requirements of your specific application. Check the datasheets and specifications provided by the manufacturer for precise details.
