Experience superior performance and unmatched versatility with the innovative Waveguide Crossguide Coupler from Pasternack.

Designed to cover frequencies ranging from 3.22GHz to 40GHz and waveguide sizes from WR-34 to WR-229, Pasternack's couplers are the ultimate solution for a wide range of applications.

Their Waveguide Crossguide Couplers are available in four coupled port designs, including SMA female, Type N female, 2.92mm, and waveguide, and offer coupling values ranging from 20dB to 50dB, making them ideal for attenuation measurements, microwave radio, and test instrumentation.

Unlike broadwall couplers, these Crossguide Couplers come in a smaller design, making them more compact and easier to integrate into your existing setup. Additionally, Waveguide Crossguide Couplers are more cost-effective than the current product offerings, ensuring that you get the best value for your investment.

One of the most distinguishing features of Pasternack's Waveguide Crossguide Couplers is the integrated load and waveguide to coax adapter in one design. This not only simplifies your setup, but also makes it more efficient, resulting in less downtime and more productivity.

The Waveguide Crossguide Couplers are made of high-quality aluminum and brass bodies, making them capable of handling high power levels up to 1.8kW. 

The PEWCP1081-40 is a prime example of our commitment to delivering high-quality products. With a typical VSWR of 1.1:1 and an intergrated N Female connector for the coupled port, this 40dB WR-229 three-port crossguide coupler is built to last. It can be mounted directly into the waveguide signal path or connected via coax for signal sampling and monitoring.
