GENERAL SPECIFICATIONS Frequency Sensitivity: ±1 dB Impedance: 50 Ω nom. Insertion Loss (above Coupling Value): 10 to 500 MHz: 1 dB max. 500 to 1000 MHz: 1.5 dB max. Directivity: 10 to 300 MHz: 20 dB min. 300 to 800 MHz: 15 dB min. 800 to 1000 MHz: 13 dB min. VSWR: 10 to 500 MHz: 1.5:1 max. 500 to 1000 MHz: 1.8:1 max. CW Input: 1 W max. Weight, Nominal: 0.007 oz. (200 mg) Operating Temperature: -- 55° to +85° General Notes: 1. The CBZ-B CaseFree series are compatible with MMIC and other similar sub-miniature components in size and process. Their low 0.130" profile allows integration within hermetic packages using silver epoxy, solder or wire bonding attachment techniques. 2. Similarly constructed Couplers are available in the CRZ-B series, with both coupled ports unterminated for use as a 4 port Bi-Directional Coupler. 3. Applications of directional couplers include the monitoring of incident and reflected power, in signal sampling for control loops, as well as test signal injection devices in BITE systems. 22Apr96 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531
