The **SWC-342F-R1** is a high-performance **WR-34 Waveguide to 2.4 mm Female Connector Adapter**. It is primarily used in millimeter-wave (mmW) applications to bridge the gap between rectangular waveguide systems and coaxial cabling systems. --- ### ## Technical Specifications The following table summarizes the key electrical and mechanical characteristics of the component: | Parameter | Specification | | :--- | :--- | | **Frequency Range** | 22.0 GHz to 33.0 GHz | | **Waveguide Size** | WR-34 (Ka-Band) | | **Connector Type** | 2.4 mm (Female) | | **Insertion Loss** | 0.35 dB (Typical) | | **VSWR** | 1.25:1 (Typical) | | **Body Material** | Aluminum / Brass | | **Body Finish** | Gold Plated / Chem Film | | **Orientation** | Right Angle | --- ### ## Key Electronic Components & Features The device functions as a passive impedance matching transformer. Its performance relies on several critical design elements: 1. **Waveguide Interface (WR-34):** The rectangular opening is designed to match the WR-34 standard. This interface guides electromagnetic waves in the **Ka-band**. The dimensions are precise to ensure the dominant $TE_{10}$ mode is maintained. 2. **Coaxial Transition (2.4 mm Female):** The 2.4 mm connector is a precision microwave connector. Unlike standard SMA connectors, the 2.4 mm interface is designed to operate without moding up to 50 GHz, ensuring clean signal integrity for the 22–33 GHz range. 3. **Right Angle Geometry:** The "R" in the part number typically denotes a **Right Angle** configuration. Inside the block, there is a probe or a step-transition that turns the signal 90 degrees while matching the 50-ohm impedance of the coax to the characteristic impedance of the waveguide. 4. **Gold Plating:** Electronic conductivity is maximized through gold plating. This prevents oxidation and minimizes "skin effect" losses, which are significant at millimeter-wave frequencies. --- ### ## Common Applications * **Radar Systems:** Used in Ka-band radar for signal routing between the antenna and the transceiver. * **Test and Measurement:** Connecting waveguide-based Signal Generators or Network Analyzers to coaxial test cables. * **Satellite Communications:** Employed in Ground Station equipment operating within the 20-30 GHz uplink/downlink bands. * **5G Research:** Used in the development of high-frequency backhaul infrastructure.
