Two small brass SMA to RP-SMA gender changer adapters

Brainwavz

Brainwavz SMA Female to RP-SMA Male Adapter 2-Pack 50 Ohm

SKU CH-6PXF-8M2MY

Two adapters convert SMA female to RP-SMA male for 50 Ohm radio connections

  • Product typeUSB to DisplayPort Adapters
  • Connect RTL-SDR dongles to SMA antennas using the RP-SMA male interface
  • 50 Ohm impedance maintains signal quality up to 6 GHz frequency range
  • Two adapters included for flexible antenna configurations and spare connections
  • Reverse polarity SMA male to standard SMA female converts gender for compatibility
  • High-quality construction supports radio astronomy and ham radio applications

Two-Pack SMA to RP-SMA Adapter

This two-pack provides SMA female to RP-SMA male gender changers for radio-frequency connections. Each adapter carries a 50 Ohm impedance rating and supports a 0-6GHz frequency range. The pack suits SDR dongles, ham radio gear and radio astronomy setups needing SMA-to-RP-SMA conversion.

Builders needing SMA-to-SMA

Buyers who require straight SMA-to-SMA or RP-SMA-to-RP-SMA couplers cannot use these adapters. Installers needing weather-sealed bulkhead connectors for outdoor masts should look elsewhere. Users wanting right-angle or tee-shaped configurations will not find them in this pack.

50 Ohm impedance rating

The 50 Ohm characteristic impedance matches standard RF test equipment, SDR dongles and most amateur radio antennas. Mismatched impedance causes signal reflections and loss, so verifying that the connected gear also specifies 50 Ohm is the single check that decides whether this adapter is the correct part.

Questions about this item

Will the SMA Female to RP-SMA Male adapter's 50 Ohm impedance match my radio equipment?

Yes, each adapter is rated at 50 Ohm impedance for optimal performance with compatible radio gear and antennas.

What frequency range does the adapter support before signal loss becomes an issue?

The adapter supports a frequency range of 0-6GHz for high-frequency signal applications.

Does the adapter generate heat or noise when used continuously with an SDR dongle?

As a passive component with no active electronics, it produces no heat or noise during continuous operation.
