Werbel Microwave Released Wideband Directional Coupler
The WMC-0.3-8-30dB-S enables consistent signal sampling across a wide 300 MHz to 8 GHz frequency range.
Updated on Sept. 30, 2026 in Semiconductors
Werbel Microwave has launched the WMC-0.3-8-30dB-S, a wideband directional coupler designed for RF systems. The device allows engineers to monitor and measure signals across multiple frequency bands using a single unit.
Why it matters
Broadband coupling capabilities simplify hardware design for systems requiring monitoring across disparate frequency ranges. By covering 300 MHz to 8 GHz, this component reduces the need for multiple specialized couplers in complex RF setups.
The unit operates from 300 MHz to 8 GHz with 30 dB nominal coupling and 0.5 dB typical insertion loss. It handles up to 20 W of input power and maintains a typical return loss of 25 dB.
The players
Werbel Microwave
An RF component manufacturer specializing in high-performance passive devices for monitoring and signal processing systems.
The details
Directional couplers function by extracting a portion of an RF signal from a transmission line for analysis without significantly impacting the main signal path. This model achieves broad frequency coverage through precision internal coupling structures that minimize insertion loss—the reduction in signal power as it passes through a component—while maintaining 23 dB of directivity. The device utilizes SMA female connectors and is supported by provided S-parameter files, which quantify the linear electrical behavior of the device, along with 2D and 3D design models.
Timeline
September 30, 2026: Werbel Microwave introduced the WMC-0.3-8-30dB-S coupler.
The Tech Race
The race in RF hardware is defined by the effort to combine broadband performance with low insertion loss. This release follows a trend of increasing signal density, where manufacturers compete to reduce the physical footprint of monitoring equipment in modern wideband communication systems.
Engineers and systems integrators can use this coupler immediately to consolidate monitoring workflows that previously required separate hardware for different frequency bands. The inclusion of CAD and S-parameter data simplifies the integration process into existing circuit simulation and board layout software.
The takeaway
This development highlights the industry movement toward multi-band consolidation in RF monitoring chains. Engineers should evaluate these S-parameter files to determine if the 0.5 dB typical insertion loss meets the power budget requirements for their specific wideband signal analysis applications.
