BNC Plug (Male) to BNC Jack (Female) Right Angle Adapter, DC-4GHz VSWR 1.25

BNC Plug (Male) to BNC Jack (Female) L-Adapter | Bayonet-lock | Brass Body

The ROSNOL ADL-B1B25A/144-94 RF adapter provides secure bayonet-lock coupling between BNC plug (male) and BNC jack (female) interfaces. Designed for precision performance, it supports 50 Ω impedance and operates from DC to 4 GHz with VSWR ≤ 1.25 (≥19.08 dB return loss). Electrical characteristics include insertion loss ≤ 0.05 × √F(GHz) dB, insulation resistance ≥ 5 GΩ, center contact resistance ≤ 1.5 mΩ, and outer contact resistance ≤ 1 mΩ. Rated for 1500 V rms test voltage and 400 V rms working voltage, this adapter handles up to 80 W at 2 GHz under standard conditions.

Constructed for durability, the center contacts are made of beryllium copper and brass with gold plating over non-magnetic nickel-phosphorus underplating. The body and coupling nut are brass with copper-tin-zinc alloy plating, while PTFE insulators and silicone rubber gaskets ensure reliable dielectric performance. The bayonet-lock mechanism supports a minimum of 500 mating cycles and axial captivation ≥15 N, with an operating temperature range of -65°C to +165°C.
