Impedance: 50 Ω nom. CW Input: 1 W max. Weight, nominal: 0.1 oz (2.8 g) Operating Temperature: -- 55° to +85°C OPTIONAL SPECIFICATIONS Coupling Values: 5 to 30 dB Frequency Bands: up to 2.5 GHz Close tolerance Coupling: ± 0.5 dB Three Port Equivalents: see CBF series General Notes: 1. Merrimac directional couplers are available in a variety of packages to suit most applications. T he CRF-A series utilizes the standard flatpack which is suitable for aerospace applications where size, weight and reliability are importa nt considerations. 2. Applications of directional couplers include monitoring of incident and reflected power,signal sa mpling for control loops and test signal injection devices in BITE. These Bi-Directional Couplers have both coupled ports available but they may be ordered with one coupled port terminated internally as in the CBF series of directional couplers. 3. Merrimac Couplers may be ordered with coupling values up to 30 dB covering selected frequency ban ds up to 65 GHz. 4. These units comply with MIL-C-15370 and can be supplied screened for compliance with additional s pecifications you specify for military and aerospace applications requiring higher reliability.
