PRODUCT SPECIFICATIONS
L-com BN126 50-Ohm Type N Coaxial T Adapter
The L-com BN126 is a three-port, T-shaped coaxial adapter with two Type N female interfaces and one Type N male interface. It provides a compact junction for compatible coaxial connections in RF test setups, equipment integration, and retrofit installations.
The adapter features a nickel-plated brass body, gold-plated brass contacts, and PTFE insulation. Its threaded Type N interfaces provide secure mechanical connections to corresponding cable and equipment connectors.
Key Features
- Exact manufacturer model: BN126.
- Three-port Type N tee configuration.
- Two N-female jacks and one N-male plug.
- 50-ohm nominal interface impedance.
- Nickel-plated brass body.
- Gold-plated brass contacts and PTFE insulation.
Coaxial Connectivity
The two female interfaces accept corresponding N-male connectors, while the male interface mates with a corresponding N-female connection. All three interfaces remain within the Type N connector family.
RF System Integration
Use the BN126 where the system design calls for a coaxial tee junction. Evaluate connected loads, operating frequency, power, and impedance behavior before installation.
Important: Do not assume that a tee adapter provides the performance of an impedance-matched RF power divider or isolated combiner. No guaranteed split ratio, port isolation, or system return-loss specification is claimed here.
Ideal Applications
- RF test fixtures requiring a Type N tee junction.
- Coaxial equipment integration.
- OEM interconnection assemblies.
- Retrofit installations using compatible Type N interfaces.
Compatible Products
The BN126 provides standard-polarity Type N connections for appropriately designed 50-ohm RF installations.
- Two N-female ports: Accept corresponding standard N-male plugs.
- One N-male port: Mates with a corresponding standard N-female jack.
Connector mating is only one compatibility requirement. Verify the operating frequency, RF power, load impedance, grounding arrangement, and performance of the complete three-port connection.
Important: Do not use connector fit alone to approve a system connection. Do not connect two transmitter outputs together through this tee without a separately verified combining design and suitable protection.
Reverse-polarity N, 75-ohm systems, BNC, SMA, and RP-SMA interfaces must not be treated as interchangeable with these connections.
