The **PCT-RSABD-DP** is a high-performance **MoCA (Multimedia over Coax Alliance) Bypass Amplifier** designed for residential and commercial cable television and data networks. It is primarily used to boost signal strength while ensuring that data communication between local devices (like DVRs and set-top boxes) remains uninterrupted during power outages. --- ### Key Electronic Specifications | Parameter | Specification | | :--- | :--- | | **Ports** | 1 Input, 1 Output (Bypass functionality) | | **Frequency Range** | 5 MHz to 1002 MHz | | **MoCA Frequency** | 1125 MHz to 1675 MHz | | **Forward Gain** | +15 dB (Typical) | | **Return Path Loss** | -0.5 dB to -1.5 dB | | **Power Consumption** | < 2 Watts | | **Surge Protection** | 6 kV Ring Wave (IEEE C62.41-1991) | --- ### Core Components and Functionality #### 1. Passive Bypass Circuitry The "DP" in the model name often refers to its **Digital/Passive** bypass capability. If the amplifier loses power, the internal electronic switch reverts to a passive state. This allows the critical RF signals to bypass the amplification circuitry so that basic cable or phone services are not lost. #### 2. Integrated MoCA Filter The unit features an internal bridge that allows MoCA signals to pass between home devices without interference. It is designed with high isolation to prevent MoCA signals from leaking out into the provider's neighborhood network, acting as a "Point of Entry" (PoE) filter and amplifier in one. #### 3. Low Noise Gallium Arsenide (GaAs) Technology Internally, the amplifier uses **GaAs (Gallium Arsenide)** transistors. Compared to traditional silicon-based amplifiers, GaAs provides: * Lower noise figures (clearer picture/faster data). * Higher linearity (less signal distortion). * Better efficiency at high frequencies. #### 4. Weather-Sealed Housing The electronic components are housed in a powder-coated, pressure-tested aluminum alloy housing. This protects the sensitive PCB (Printed Circuit Board) from: * **EMI/RFI Interference:** Shielding against outside radio signals. * **Environmental Corrosion:** Protection against salt spray and humidity. --- ### Example Installation Schematic ```mermaid graph LR A[Street/Drop Cable] --> B[PCT-RSABD-DP Input] B --> C{Power Status} C -- Power ON --> D[+15dB Boosted Signal] C -- Power OFF --> E[Passive Bypass Mode] D --> F[Home Network/TV] E --> F ```
