The part number **8AT-36-R** typically refers to a high-performance **Attenuator** (specifically an SMA Fixed Attenuator). These components are essential in RF (Radio Frequency) and microwave engineering to reduce the power of a signal without distorting its waveform. --- ### 1. Key Technical Specifications Based on standard industry naming conventions for the "8AT" series, here are the primary specifications: | Parameter | Typical Value | | :--- | :--- | | **Component Type** | Fixed Coaxial Attenuator | | **Attenuation Value** | 36 dB | | **Frequency Range** | DC to 18 GHz (common for this series) | | **Connector Type** | SMA (Male to Female) | | **Impedance** | 50 Ohms | | **Power Rating** | 2 Watts (Average) | | **RoHS Compliant** | Yes (indicated by the "-R" suffix) | --- ### 2. Physical Construction The device is built to withstand high-frequency environments and maintain signal integrity. * **Housing:** Usually stainless steel or passivated gold-plated brass. * **Dielectric:** PTFE (Teflon) for low loss and high thermal stability. * **Contact Pins:** Beryllium copper with gold plating for maximum conductivity and durability over multiple mating cycles. * **Form Factor:** Cylindrical plug-and-jack design. --- ### 3. Core Functions and Applications The **8AT-36-R** serves several critical roles in electronic systems: #### A. Power Level Adjustment It reduces high-power signals to a level compatible with sensitive measurement equipment (like Spectrum Analyzers) to prevent "clipping" or hardware damage. #### B. Impedance Matching By placing an attenuator between a source and a load, it can improve the Voltage Standing Wave Ratio (VSWR), reducing signal reflections that cause interference. #### C. Isolation It provides isolation between different stages of an RF circuit, ensuring that changes in one stage do not adversely affect the performance of the preceding stage. --- ### 4. Decoding the Part Number | Segment | Meaning | | :--- | :--- | | **8AT** | Series designation (often refers to 8.5mm body or specific manufacturer series). | | **36** | The attenuation value in decibels (dB). | | **R** | RoHS (Restriction of Hazardous Substances) Compliance. | ---
