4-Way RF Power Divider, SMA Female, 2–18 GHz, 20 W

The PDWS-0218-4 is a 4-way SMA RF power divider designed for broadband microwave applications from 2 to 18 GHz. It distributes one input signal across four equal output paths while maintaining low insertion loss, solid port-to-port isolation, and controlled amplitude and phase balance across the operating band. It is a practical solution for professional RF systems, laboratory setups, telecom subsystems, radar instrumentation, and automated production test environments.

Why choose this 4-way RF power divider

• Broadband 2-18 GHz coverage for multi-band RF and microwave applications.
• 4-way signal distribution, ideal when one RF input needs to feed multiple signal paths with good consistency.
• Low insertion loss of ≤1.6 dB (excluding theoretical split loss), helping reduce the additional attenuation introduced by the divider.
• Isolation >18 dB between output ports, supporting more stable signal distribution and reduced interaction across channels.
• Controlled port balance with amplitude balance ≤ ±0.4 dB and phase balance ≤ ±6°, suitable for a wide range of professional RF and microwave applications.
• 20 W CW input power handling as divider and 1 W as combiner, offering flexibility in both lab and system-level use.
• Compact, industrial-grade construction with SMA female connectors, 50 Ω impedance, and an operating temperature range of -45 to +85 °C.
• RoHS and REACH compliant, making integration easier in regulated industrial and commercial projects.

Typical applications

• RF test and measurement benches for multi-line signal distribution, calibration paths, and reference routing
• Broadband microwave setups for validation, characterization, and automated production testing
• Telecom and wireless subsystems that require one signal to be distributed across multiple stages or modules
• Radar platforms and RF instrumentation operating over wide frequency ranges
• Professional RF architectures for signal splitting and low-power combining in lab and industrial environments

Designed for reliable RF integration

This 4-way broadband RF power divider is intended for engineers, integrators, and test environments that require repeatable electrical performance in a compact format. Its combination of controlled VSWR, moderate insertion loss, good port isolation, and consistent channel balance makes it well suited for design-in activities, validation benches, and long-term use in professional RF chains.

The mechanical design also supports reliable integration in demanding environments, with a painted aluminium housing, passivated stainless-steel connector bodies, and gold-plated BeCu center pins. When a signal needs to be distributed across four paths with compact size, mechanical robustness, and dependable RF performance, the PDWS-0218-4 provides a practical solution for broadband applications.
