1 / 1 page ![]() Surface Mount B-Package Outline GENERAL SPECIFICATIONS Impedance: 50 Ω nom. CW Input: 1 W max. Weight, nominal: 0.1 oz (2.8 g) Operating Temperature: -- 55° to +85°C General Notes: 1. Directional couplers find applications in monitoring of incident and reflected power, sampling for control loops as well as signal injection devices in BITE systems. 2. These Directional Couplers are 3 port devices with one port internally terminated. They also may be used back-to-back as Dual Directional Couplers, or ordered with both coupled ports available, as Bi-Directional Couplers in the CRG-B series. 3. Optional performance characteristics for this series include frequencies up to 2.5 GHz, coupling from 5 to 30 dB, close tolerance coupling and more.
