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

Description

The SMA Tee-Type Adapter (Male-Male-Female) is a precision RF component designed to branch a signal or create a series connection between two female-terminated ports and one male-terminated cable. The SMA (Sub-Miniature version A) interface is the preferred choice for high-frequency applications where space is limited but electrical performance is critical. Precision-machined to maintain signal integrity up to 4 GHz, this adapter is ideal for IoT development, SDR (Software Defined Radio) arrays, and 4G LTE/5G sub-6GHz prototyping.

The adapter features a Gold-Plated Brass body for superior conductivity and corrosion resistance, with Gold-Plated center contacts on all ports to ensure maximum signal fidelity and minimal contact resistance. The configuration includes two SMA Male plugs (with 1/4″-36 threaded coupling nuts) and one SMA Female jack. This specific M-M-F layout is frequently used to interconnect two female-mounted modules (such as a filter and a low-noise amplifier) while providing a monitoring or injection port for an SMA male-terminated cable.

Key Technical Advantages

• High-Frequency Precision: Rated for operation from DC to 4 GHz, providing superior VSWR performance and consistent 50 Ohm impedance matching for high-speed data transmission.

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

• Space-Efficient Design: The sub-miniature footprint allows for high-density signal splitting in space-constrained enclosures where larger connectors like N-Type or BNC cannot fit.

• Threaded Mechanical Security: The precision threaded interface ensures a high-retention, vibration-resistant connection that maintains electrical stability through hundreds of mating cycles.

• Professional Signal Integrity: Utilizes high-grade PTFE (Teflon) insulators to minimize insertion loss and prevent unwanted signal reflections in sensitive RF signal paths.
