Telegärtner Adaptador coaxial inter-series SMA macho a N hembra 50 ohmios DC-18 GHz

Wideband performance from DC to 18 GHz with VSWR ≤ 1.25 makes this Telegärtner coaxial adapter a precision interconnect for RF systems. It converts an SMA male interface to an N female jack while maintaining a 50 Ω impedance across the entire frequency range.

Overview

The Telegärtner Inter-Series adapter (model 100024201) provides a reliable transition between SMA and N connector types. Its brass body with nickel plating and gold-plated inner conductor ensure low contact resistance and long-term durability. PTFE insulation supports stable electrical characteristics over a wide temperature range from -65 °C to +165 °C.

What stands out

• Broadband operation: DC to 18 GHz
• Low VSWR: ≤ 1.25 across the band
• 50 Ω impedance matching
• Gold-plated inner conductor for low contact resistance (≤ 3 mΩ)
• Nickel-plated brass body for corrosion resistance
• Wide operating temperature: -65 °C to +165 °C
