Description
The BNC Male to SMA Male Adapter is a versatile “between-series” RF component designed to provide a reliable direct transition between two distinct coupling architectures. It features a BNC Plug (Male) on one side, utilizing the classic bayonet-style quick-lock mechanism, and an SMA Plug (Male) on the other, featuring a standard hexagonal coupling nut and center pin for secure threaded mating.
This adapter is essential for engineers and technicians who need to join two female ports-typically connecting a BNC-equipped oscilloscope or signal generator directly to an SMA-equipped device or cable. The precision-machined body ensures a constant 50 Ohm impedance, significantly reducing signal reflections and power loss. Constructed with a high-quality nickel or gold-plated brass body and PTFE (Teflon) insulation, it maintains exceptional signal integrity and low VSWR up to 4 GHz. Its rugged, double-male design is built to withstand frequent mating cycles in both demanding field operations and laboratory environments.
Key Technical Advantages
-
Direct Series Conversion: Provides a seamless, low-loss transition between BNC and SMA standards, eliminating the need for intermediate patch cables.
-
Rapid Bayonet Mating: The BNC male side allows for instantaneous connection and disconnection with a simple quarter-turn, ideal for rapid bench testing.
-
Precision Threaded Coupling: The SMA male side features a high-strength hexagonal nut that ensures a stable, vibration-proof connection for high-frequency signals.
-
Superior RF Shielding: The solid brass construction ensures a continuous ground path, providing excellent protection against EMI and RFI interference.
-
Maximum Conductivity: High-purity gold plating on the center contact pins ensures low contact resistance and superior corrosion resistance over time.
Key Features
-
Double-Male Configuration: Features a BNC Plug (with pin) and an SMA Plug (with pin) for joining two female jacks or ports.
-
