The **SWC-90SF-R5** is a high-precision Waveguide-to-Coax adapter designed for millimeter-wave (mmWave) applications. It is specifically engineered to interface standard rectangular waveguides with coaxial systems in the **E-Band** frequency range. --- ### 1. Technical Specifications The following table highlights the primary electrical and mechanical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Waveguide Size** | WR-12 (E-Band) | | **Coaxial Connector** | 1.0mm (Female) | | **Frequency Range** | 60 GHz to 90 GHz | | **VSWR (Typical)** | 1.5:1 | | **Insertion Loss** | 0.8 dB (Typical) | | **Body Material** | Gold-Plated Brass / Aluminum | | **Orientation** | Right Angle | --- ### 2. Key Electronic Components & Design The "Electronic" functionality of this part is passive, relying on physical geometry and material properties to manage electromagnetic waves: * **WR-12 Waveguide Interface:** This is the hollow metallic structure designed to guide electromagnetic waves between 60 and 90 GHz. The dimensions are precise to prevent signal dispersion. * **1.0mm Coaxial Connector:** The 1.0mm connector is used because it supports frequencies up to 110 GHz. The "Female" designation refers to the center conductor receptacle. * **Right-Angle Transition:** The "R" in the part number often signifies a Right-Angle configuration. This involves an internal probe or "launcher" that converts the TE10 mode of the waveguide into the TEM mode of the coaxial cable. * **Gold Plating:** To minimize skin effect losses and prevent oxidation at high frequencies, the internal and external surfaces are typically plated with high-purity gold. --- ### 3. Common Applications This part is essential in high-frequency laboratories and telecommunications infrastructure, including: 1. **5G/6G Research:** Testing transceivers and antennas in the E-band spectrum. 2. **Radar Systems:** Used in automotive radar and high-resolution imaging sensors. 3. **Test & Measurement:** Connecting a Waveguide-based Antenna to a Coaxial-based Vector Network Analyzer (VNA). ---
