Directional couplers are useful for monitoring incident and reflected power, signal sampling, control loops and BITE. 2. The CBF-A series consists of 3 port devices with one port internally terminated. They may be used back-to-back as dual directional couplers. The CRF-A series of bi-directional couplers provides direct access to both coupled ports. 3. Merrimac couplers may be ordered with specific coupling values up to 30 dB and over selected fr……
