elite cr -38 multi-throw dc-22ghz normally open the cr-38 switch is a broadband, multi-thro w, electromechanical coaxial switch designed to switch a microwave signal from a common inpu t to any of 3, 4, 5, or 6 outpu ts. the characteristic impedance is 50 ohms. the switches are small using the popular connector spacing on a 1.062" dia. circle. each position has an individual actuator mechanism allowing random position sele ction. this also gives the minimum switc hing time. with the normally open a ct uator, all paths are open when the switch is de-energized. specifications rf contacts: b reak bef ore make actuator v olt ag e (v dc) 20 o c 12 15 28 curren t (ma) 170 136 140 switching time: 15 msec max c onnectors: sma (f) weight: 6 oz . max t emperature range: -55 o c to +85 o c (operating) shock: mil-std-202 method 213, condition d (500g non operating) vibration: mil-std-202 method 214, condition d (10g rms non operating) humidity: mois ture seal a vailable typical contact life: 5 m illion cycles rf pow er handling spec ifi cations dc-6 ghz 6-12 ghz 12-18 ghz 18-22 ghz vswr (max) 1.25:1 1.40:1 1.50: 1 1. 80:1 inse rt ion loss (m in) 0.20 db 0.40 db 0.50 db 0.60 db isola tion (max) 70 .0 db 60 .0 db 60 .0 db 50 .0 db t ypical performance 0.01 22.0 frequency ghz 0.0 0.4 bd li bd noitalosi 90 80 70 60 15 25 ruter ssol n 0.01 22.0 frequency ghz 3000 800 400 200 80 40 10 pow w( wc re )stta 0.1 1.0 4.0 10 18 22 frequency ghz standard sma connectors t el: (800) 351-7368 www.teledynecoax.com email: coax@teledyne.com specifications subject to change without notice. 10/2007 insertion loss repeatability (1 million cycles): dc to 6 ghz: 0.05 db dc to 20 ghz: 0.1 db
