CX-3
CXG SERIES DC to 700 MHz COAXIAL MATRIX
CYTEC's CXG Series of coaxial tree switch matri-
ces are available as 4x8 or 8x8 nonblocking con-
figurations in 50 or 75 ohm characteristic imped-
ance. The tree switch topology shown in Fig. 7,
provides excellent attenuation and crosstalk speci-
fications from DC to 700 MHz. The use of electro-
mechanical relays make these systems completely
bidirectional and capable of hot switching signals
up to 24 watts. 50 ohm systems are available with
BNC, SMA or other user specified connectors. 75
ohm systems are available with BNC or SMB con-
nectors. Any of CYTEC's standard control mod-
ules may be specified as well as the MC/2 Keypad
manual control.

CXF SERIES FULL FANOUT 5-500MHz COAXIAL MATRIX
This system is a nonblocking (any input to any output), full fan out (any input to any or all outputs), 50
ohm coaxial switch matrix available in 4x8 or 8x8 configurations as shown in Fig. 8. Larger configura-
tions can be supplied using multiple Expansion Chassis and a MESA Control Chassis. Systems are built
with BNC or SMA as standard connectors. Other connector styles available on request. The matrix has
LED visual display of latched switch paths and is available with any of the standard control modules.
