Description

F-Substrate connectors are specialized surface-mount (SMT) or PCB-mounted RF coaxial connectors designed for high-frequency applications where space-saving and signal integrity are critical. Below is a detailed breakdown of their features, types, and applications. 1. What Are F-Substrate Connectors? Purpose: Provide a low-loss RF connection between a PCB and coaxial cable. Mounting Style: Surface-mount (SMT) or through-hole (THT). Frequency Range: Typically DC to 6 GHz (some up to 12 GHz for high-end models). Impedance: 50Ω (standard for RF) or 75Ω (video applications). Common Uses: IoT/Wi-Fi/Bluetooth modules 5G small cells Automotive radar (24 GHz, 77 GHz) Medical RF devices 2. Types of F-Substrate Connectors A) Standard SMT F-Substrate (Edge Launch) Mounting: Soldered directly to PCB pads. Example: Hirose Electric U.FL Series (miniature, up to 6 GHz). B) Right-Angle F-Substrate (Vertical Mount) Use Case: Space-constrained designs (e.g., drones, wearables). Example: I-PEX MHF® Series (up to 10 GHz). C) High-Frequency F-Substrate (12+ GHz) Applications: mmWave (5G, automotive radar). Example: Rosenberger SMP-Mini (DC-40 GHz). D) Waterproof/IP-Rated F-Substrate Use Case: Harsh environments (industrial, automotive). Example: TE Connectivity STRADA Whisper (sealed RF connectors).
