The part number **68-10-R** typically refers to a **High-Power Attenuator** or a specialized **RF/Microwave Termination** component. While several manufacturers use similar numbering schemes, it is most commonly associated with **API Technologies (Inmet)** or **Aeroflex/Weinschel** components. --- ### 1. Component Overview An attenuator is an electronic device that reduces the power of a signal without appreciably distorting its waveform. The "68-10-R" specifically breaks down into technical specifications: | Feature | Specification | | :--- | :--- | | **Component Type** | Fixed Coaxial Attenuator | | **Attenuation Value** | 10 dB | | **Power Rating** | Often 50 Watts to 100 Watts (Series dependent) | | **Frequency Range** | DC to 18.0 GHz (Standard for this series) | | **Impedance** | 50 Ohms | | **RoHS Status** | "R" suffix usually denotes RoHS Compliance | --- ### 2. Physical & Technical Characteristics These parts are designed for high-reliability environments and include several key design features: * **Cooling Mechanism:** High-power attenuators like the 68 series usually feature **cooling fins** (anodized aluminum) to dissipate heat generated by the reduction of signal power. * **Connectors:** Usually equipped with **Type N** or **SMA** connectors. * **Construction:** * **Housing:** Stainless steel or Aluminum. * **Resistive Element:** Thin-film or Thick-film ceramic. --- ### 3. Common Applications The 68-10-R is primarily used in RF testing and telecommunications: 1. **Power Leveling:** Protecting sensitive test equipment (like Spectrum Analyzers) from high-power transmitters. 2. **Impedance Matching:** Improving the VSWR (Voltage Standing Wave Ratio) between mismatched components. 3. **Signal Simulation:** Simulating path loss in long-distance wireless communication links. 4. **Base Stations:** Used in cellular infrastructure to balance signal strength across different sectors. --- ### 4. Technical Summary Table | Parameter | Typical Value | | :--- | :--- | | **Input Power (Avg)** | 50 Watts @ 25°C | | **Peak Power** | 500 Watts to 1 kW (Pulse dependent) | | **VSWR (Max)** | 1.35:1 | | **Attenuation Accuracy** | ± 0.5 dB to ± 1.0 dB | | **Operating Temp** | -55°C to +125°C | ---
