C−1830−10 coupling vs. frequency plot.

July 20, 2023 -- Werbel Microwave presents an impressive array of features in our latest offering. The C-1830-10 from Werbel Microwave is an ultra-wideband directional coupler with exceptional performance across frequencies from 0.3 to 8 GHz. It offers excellent coupling flatness, good directivity, and can handle up to 20 W of power. This coupler is well-suited for lab testing and power monitoring applications, among others. With its ultra-wide bandwidth, spanning from 0.3 to 8 GHz, it eliminates the need to switch components for different frequency bands in most lab testing scenarios. The coupler also provides high directivity (24 dB typ.), minimizing detrimental effects from output mismatches. Additionally, it offers excellent coupling flatness of ±0.8 dB typ., eliminating the need for compensation circuits in many cases.
