Reverse Polarity SMA Male to SMA Male Adaptor

TYPE SMA is one kind of coaxial connectors that is widely applied, with small-sized thread coupling. Characteristic impedance is 50Ω. The characteristic of connectors is in wide frequency range, excellent performance, high reliability. They are used in connection with RF cable or micro-strip line in RF circuit of the WLAN system, controlled program, microwave equipment and the digital communication system. The frequency can be up to 18GHz by using semi-rigid or semi-flex cable.

Reverse Polarity SMA Male to SMA Male Adaptor

  1. Reverse Polarity SMA Conversion: Bridges RP-SMA male interfaces – solves polarity mismatch for RF devices (e.g., antennas, routers)
  2. Ultra-High Frequency Support: Covers DC-12.4GHz (semi-rigid cable up to 18GHz) + low insertion loss (≤0.15dB@6GHz) for high-bandwidth applications
  3. Extreme Environmental Resilience: Operates -55°C~+155°C, withstands 10g vibration (10~2000Hz) – ideal for harsh industrial/field setups
  4. Low VSWR & High Reliability: VSWR as low as 1.07 (semi-rigid, straight), 500+ mating cycles, and 1000V withstand voltage – stable, long-lasting performance
  5. Precision Electrical Specs: Center contact resistance ≤3mΩ, insulation resistance ≥5000MΩ – minimal signal loss for critical RF links
