APH-HDBNCP-SMAP is a 50 ohm HD BNC plug to SMA plug adapter designed for RF signal interconnection applications. The adapter features a frequency range of DC to 6 GHz with a maximum VSWR of 1.05 at 6 GHz, ensuring excellent signal integrity across the operating bandwidth. The connector body and bayonet sleeve are constructed from brass with nickel plating, while the outer contact uses beryllium copper with nickel plating and the inner contact is brass with gold plating; the insulator is PTFE for reliable electrical performance. The adapter operates reliably over a temperature range of -65°C to +165°C and is rated for a minimum of 500 mating cycles, making it suitable for demanding RF test, measurement, and communication systems where reliable impedance matching and low signal loss are critical.
