Model WMC-0.5-20-20dB-S from Werbel Microwave is a directional coupler that covers 500 MHz to 20 GHz with broadband flat coupling response, high directivity, and excellent return loss performance. Many military and telecom bands are covered within a single, small size enclosure. Extremely flat ±0.6dB typical coupling passband ripple makes for high accuracy and low signal degradation in AGC loops and sensing applications. From upper UHF to lower K bands. Designed, assembled and tested in USA.
