CBG-A Series WIDEBAND DIRECTIONAL COUPLER 10 to 1000 MHz / Low 0.2" Profile / Minimal Size and Weight / Surface Mount Package PRINCIPAL SPECIFICATIONS Model Number GENERAL SPECIFICATIONS Coupling Frequency Coupling, Tolerance, Sensitivity, dB dB dB Bandwidth MHz ±1 ±1 10 to 1000 10 to 1000 CBG-11A-500 CBG-20A-500 11 20 ±1 ±1 Coupling Value is referred to Input Port General Notes: 1. Directional couplers find applications in monitoring incident and reflected power, sampling for control loops as well as signal injection in BITE systems. 2. The 0.25" square surface mount package used in the CBG-A series has been designed for 50 Ω coplanar systems to optimize RF performance while still achieving the small size and low profile of surface mount devices. The Kovar input leads are designed to suit a variety of mounting situations simply by cutting them to the desired length.
