    Absorptive RF Switching with Integrated Logic
    The HRF‑SW1001 is a single‑pole double‑throw absorptive RF switch designed for precision routing of RF signals up to 2.5 GHz. It incorporates CMOS logic for simple control and DC coupling for signal continuity, all within a compact 3 mm × 3 mm 12‑lead QFN package. The device provides internal termination on the unused path, improving signal stability and reducing reflection. These characteristics allow the switch to be implemented in signal path selection and routing systems requiring high isolation. The design is optimized for 75 Ω impedance systems, enabling compatibility with a range of RF front ends and electronics components. For systems that include a Digital Signal Processor, this component allows programmable RF path control with minimal footprint.

    Frequency Performance and Electrical Parameters
    Operating from DC to 2.5 GHz, the HRF‑SW1001 provides reliable performance in high-frequency circuits. At 2.0 GHz, the insertion loss is typically 0.9 dB, increasing slightly to 1.1 dB at 2.5 GHz. Isolation remains strong across the range, reaching 44 dB at 2.0 GHz and 39 dB at higher frequencies. The device maintains a return loss between −15 and −20 dB and supports linear operation up to an input IP3 of approximately 35 dBm. With a 1 dB compression point near 25 dBm, the switch supports both signal integrity and robustness under moderate RF power. Its VDD ranges from 3.3 V to 5.5 V, allowing easy integration with both traditional and modern integrated circuits, including those controlled by Digital Signal Processor architectures.

    Packaging, Availability, and Stock Format
    The HRF‑SW1001 is packaged in a 12‑lead QFN with exposed pad for thermal and RF performance. Its compact footprint and lead arrangement allow easy surface-mount assembly. Versions are available in standard cut tape, full reel, and evaluation board configurations. The device is classified as active and is sold as new and original stock. Minimum order quantity begins at one unit, with availability listed across global channels. This RF switch is designed to meet the demand for reliable signal routing among advanced electronics components, particularly in environments where space, signal clarity, and control flexibility are critical. Its interface simplicity makes it suitable for fast integration into Digital Signal Processor-based systems.



    Product Advantages

    Signal Integrity Through Absorptive Switching
    By terminating the unused port with an internal matched load, the HRF‑SW1001 preserves signal quality and reduces reflections. This is particularly important in systems using high-speed integrated circuits, where return loss and isolation can affect overall system accuracy. With isolation up to 44 dB and return loss maintained across the band, it ensures clean path transitions. The integration with CMOS logic also removes the need for external biasing, simplifying the control interface when connected to a Digital Signal Processor.

    Compact Format and Simplified Routing
    Measuring just 3 mm × 3 mm, this switch saves valuable board space, especially in densely packed RF subsystems. The QFN package with an exposed pad ensures effective grounding and thermal performance. Because the RF paths are DC-coupled, signal continuity is maintained without external capacitors. This makes the HRF‑SW1001 ideal for integration into modular assemblies involving various electronics components and allows for direct routing of RF signals controlled via a Digital Signal Processor system.

    Flexible Supply and Logic Compatibility
    With a supply range from 3.3 V to 5.5 V and CMOS-compatible control logic, this device fits easily into both legacy and modern RF platforms. Logic control is straightforward, reducing component count and complexity for users implementing switch control via firmware or real-time hardware such as a Digital Signal Processor. These integrated circuits are effective in both prototyping and deployment stages due to their consistent electrical behavior, ease of assembly, and clear electrical specifications.



    Use Scenarios

    RF Signal Path Management in Front-End Modules
    In radio frequency front-end subsystems, the HRF‑SW1001 allows engineers to control signal routing between multiple filter or antenna paths. Its high isolation and low insertion loss support cleaner transitions, making it suitable for systems incorporating Digital Signal Processor-based control. These integrated circuits can enable active signal path switching with minimal added power consumption or layout complexity.

    Embedded Wireless Systems and Test Platforms
    This switch is suited for integration into embedded wireless platforms requiring dynamic signal redirection, such as signal switching between bands or modules. The DC-to-2.5 GHz bandwidth ensures flexibility across multiple RF standards. Controlled by a Digital Signal Processor, the device can be used in real-time signal selection scenarios, forming a functional interface between multiple RF subsystems and other electronics components.

    High-Frequency Prototyping and Evaluation Applications
    The availability of evaluation board configurations enables fast testing of switch behavior, insertion loss, and frequency-dependent characteristics. These evaluations can be driven using software or test firmware on a Digital Signal Processor, allowing users to validate the switch’s interaction with surrounding integrated circuits. With performance metrics predictable across frequency and voltage, the HRF‑SW1001 supports a seamless transition from prototype to production.
