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

Description

The UHF Tee-Type Adapter (Male-Male-Female) is a rugged RF component designed to branch a signal or create a series connection between two female-terminated ports and one male-terminated cable. Utilizing the industry-standard PL-259 (Male) and SO-239 (Female) interfaces, this adapter is built for mechanical resilience. While standard UHF connectors are often used for lower frequency bands, this high-specification variant utilizes precision internal geometry and superior dielectrics to maintain performance up to 4 GHz, supporting advanced high-power antenna manifolds and ruggedized laboratory setups.

The adapter features a Nickel-Plated Brass body for maximum physical strength and environmental protection. To ensure reliable signal conductivity, it is equipped with Gold-Plated or Silver-Plated center contacts that provide low contact resistance through repeated mating cycles. The configuration includes two UHF Male plugs and one UHF Female jack, all featuring standard 5/8″-24 threads. This specialized M-M-F layout is frequently used to interconnect two female-mounted pieces of equipment (such as a duplexer and a power amplifier) while providing a monitoring or signal injection port for a standard UHF male cable.

Key Technical Advantages

• Robust Power Handling: Physically larger and more durable than SMA or BNC connectors, allowing it to manage the high wattage levels typical of base station transmitters.

• Extended Spectrum Range: Precision-tuned to operate up to 4 GHz, providing greater versatility for modern communication testing compared to standard 300 MHz rated UHF hardware.

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

• Vibration-Resistant Threaded Interface: The heavy-duty threaded coupling ensures a secure, high-retention connection that is ideal for demanding mobile, maritime, and field operations.

• Professional Signal Path: Utilizes high-grade PTFE (Teflon) insulators to provide superior thermal stability and minimize signal loss in critical high-power paths.
