Telegärtner Inter-Series Coaxial Adapter SMA Male to FME Male 50 Ohm

This Telegärtner Inter-Series adapter bridges two of RF engineering's most trusted connector families in a single precision component. While many adapters introduce measurable loss or reflection, the J01703A0009 keeps insertion effects to a minimum across DC to 3 GHz, making it a dependable inline solution for test benches, antenna feeds, and modular RF assemblies. The straight body geometry and free-hanging design mean it fits naturally into cable runs without adding strain or awkward routing.

Highlights

• Connector A: SMA male (plug) with gold-plated center contact for low contact resistance and long-term stability.
• Connector B: FME male (plug), ideal for mobile and quick-connect RF applications.
• 50 Ω impedance matched to standard RF systems, with VSWR ≤ 1.3 up to 3 GHz.
• Nickel-plated brass body for mechanical robustness and corrosion resistance.
• PTFE insulator ensures consistent dielectric performance across the operating temperature range.

In daily use

Technicians working with cellular, Wi-Fi, or telemetry equipment often need to convert between SMA and FME interfaces without re-terminating cables. This adapter screws directly onto an SMA jack and presents a male FME port, enabling quick attachment of FME-equipped antennas or cables. The gold center contact and nickel body resist oxidation, so repeated mating cycles do not degrade signal quality. With a wide temperature rating from -40 °C to +85 °C, it can be used in outdoor enclosures or vehicle installations where thermal swings are common.
