Impedance: 50 Ω nom. Frequency Sensitivity: ±1 dB, max. 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. Bi-directional couplers in the CRZ-B CaseFree series are size and process compatible with MMIC and other similar sub-miniature components. Their low 0.130" profile facilitates integration with hermetic packages using silver epoxy, solder or wire bonding attachment methods. 2. Similarly constructed couplers are available in the CBZ-B series with the "reverse coupled port" terminated for use as a 3-port directional coupler. 3. Applications of directional couplers include monitoring of incident and reflected power, signal sampling for control loops and test signal injection devices in BITE.
