N-Type Tee-Type Adaptor (M-M-F), DC to 4 GHz

Description

The N-Type Tee-Type Adapter (Male-Male-Female) is a precision RF component designed to branch a high-power signal or create a series connection between two female-terminated ports and one male-terminated cable. The N-Type interface is renowned for its mechanical robustness and ability to handle significantly higher power levels than miniature connectors. Precision-machined to maintain signal integrity up to 4 GHz, this adapter is ideal for 4G LTE/5G sub-6GHz infrastructure, high-power amplifiers, and outdoor wireless installations.

The adapter features a Nickel-Plated or Tri-Metal Plated Brass body for superior durability and weather resistance, with Gold-Plated center contacts to ensure maximum signal conductivity and low contact resistance. The configuration includes two N-Type Male plugs with threaded coupling and one N-Type Female jack. This specific M-M-F layout is frequently used to interconnect two female-mounted pieces of equipment (such as a filter and an amplifier) while providing a monitoring or injection port for a standard N-Type male cable.

Key Technical Advantages

• High-Frequency Stability: Rated for operation from DC to 4 GHz, providing superior VSWR performance and lower insertion loss compared to standard commercial-grade adapters.

• Specialized M-M-F Layout: Streamlines complex RF chains by eliminating the need for multiple gender changers when connecting two female chassis ports to a single male cable.

• Robust Power Handling: Engineered to manage the high wattage typical of cellular base stations and transmitter assemblies without signal degradation.

• Weatherproof Threaded Interface: Provides a secure, vibration-resistant connection that is ideal for both laboratory test benches and harsh outdoor environments.

• Precision Signal Integrity: Utilizes high-grade PTFE (Teflon) insulators to maintain a consistent 50 Ohm impedance, preventing reflections in high-power signal paths.
