Description

Right-angle SMA connectors with precise length specifications are critical for PCB designs, compact RF systems, and antenna integration where space constraints and signal integrity are key. Below is a detailed breakdown of their types, applications, and selection criteria. 1. Key Features of Length-Specified SMA Right-Angle Connectors ✔ 90° Bend – Saves space in tight layouts (e.g., PCBs, drones, IoT devices). ✔ Precision Length Control – Ensures consistent impedance and minimizes signal reflections. ✔ Gold-Plated Contacts – Low insertion loss (<0.2 dB) and corrosion resistance. ✔ Frequency Range – DC to 18 GHz (depends on model). ✔ Mounting Styles: PCB Edge Mount – Direct solder to RF traces. Panel Mount – Screw-secured for rugged use. Cable Mount – For flexible RF assemblies. 2. Common Types & Length Specifications A) Standard SMA Right-Angle (6–12mm Length) Use Case: General RF modules, Wi-Fi/Bluetooth PCBs. Example: Amphenol RF 132360 (6mm, edge launch). B) Extended-Reach SMA Right-Angle (15–25mm) Use Case: Antenna feeds, shielded enclosures. Example: Huber+Suhner 11_SMA-50-2-14/111_N (18mm, gold-plated). C) Ultra-Short SMA Right-Angle (3–5mm) Use Case: High-density PCBs (mmWave, 5G small cells). Example: Rosenberger SMP-Mini (4mm, up to 40 GHz). D) Waterproof IP67 Right-Angle SMA Use Case: Outdoor antennas, marine/avionics. Example: TE Connectivity 5-1814832-1 (IP67, 12mm length).
