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

Description

The SMA Tee-Type Adapter (Male-Male-Male) is a precision-machined RF component designed to branch a single signal path into two, or to combine two signals into one, using three standard SMA Male interfaces. The SMA (Sub-Miniature version A) interface is renowned for its excellent electrical performance and compact size, making it the preferred choice for high-frequency board-level and module-to-module connections. This adapter is precision-engineered to maintain signal integrity up to 4 GHz, making it ideal for IoT development, 4G LTE/5G sub-6GHz testing, and laboratory environments.

The adapter features a Gold-Plated Brass or Stainless Steel body for superior durability and minimal signal loss. The Gold-Plated center contacts ensure maximum conductivity and a low-resistance signal path. All three ports feature standard threaded coupling (1/4″-36 thread), providing a secure, vibration-resistant connection. This specific M-M-M configuration is often utilized to interconnect two female-terminated coaxial cables with a female chassis-mounted port on a filter, amplifier, or SDR (Software Defined Radio) module.

Key Technical Advantages

• Optimized High-Frequency Performance: Precision-tuned for operation from DC to 4 GHz, offering low VSWR and consistent 50 Ohm impedance matching for high-speed wireless data.

• Triple-Male Layout: A specialized configuration that facilitates unique interconnection needs in dense RF environments, reducing the requirement for extra cables or adapters.

• Compact and Lightweight: The sub-miniature footprint allows for high-density signal splitting in space-constrained enclosures where BNC or N-Type connectors are too large.

• Superior Mechanical Stability: The threaded interface provides a high-retention, secure connection that remains stable even under mechanical stress or vibration.

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