commercial ccrt -53 internal t erminations dc- 26 .5ghz sp dt swit ch failsafe the cc rt -53 switch is an internally terminated, broadband, spd t, electromechanical coaxial switch designed to switch a microwave signal from a common input to either of two output s. the characteristic impedance is 50 ohms. internal terminations provide an impedance match for the unselected port. the switches are small with the minimum sp acing that is comp atible with sma connectors. the cc rt -53 is available with either a failsafe or latching actuato r. specifications rf contacts: b reak bef ore make actuator v olt ag e (v dc) 20 o c 12 15 28 curren t (ma) 420 350 200 switching time: 20 msec max t ermination s: 50 o hm 2 wa tts cw max connectors: sma (f) we igh t: 2.65 oz. max t emperature range: -40 o c to +65 o c (operating) shock: mil-std-202 method 213, condition d (500g non operating) v ibration: mil-std-202 method 214, condition d (10g rms non operating) humidity: mois ture seal a vailable typical contact life: 5 million cycles rf p ower handling (non-terminate d) h = 1.75 max. std model h = 1.86 max. ttl model sp ec ifi cation s dc-6 ghz 6-12 ghz 12-18 ghz 18-26.5ghz 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 0.70 db isola tion (max) 70 .0 db 60 .0 db 60 .0 db 50 .0 db 3000 800 400 200 80 40 10 pow w( wc re )stta 0.1 1.0 4.0 10 18 26.5 frequency ghz standard sma connectors t ypical performance 15 25 ruter ssol n 0.01 26.5 frequency ghz 0.01 26.5 frequency ghz 0.0 0.4 bd li bd noitalosi 90 80 70 60 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
