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.
