Cytec CXAR Series of Switching Systems

CXAR products are 50 or 75 ohm coax switch modules with mechanical or solid state switches. They can be configured to drive from 16 to 256 switch points and are intended to be used for signal from DC to 2.5 GHz depending on the configuration. Most of the modules used in these systems are 1xN multiplexers that can be combined to form larger multiplexers or matrices. Control options include 10/100BaseT Ethernet LAN, RS232, GPIB or optional manual control. There are four different types of switch modules available:

Reed Relays -- Bi-directional mechanical relays. Limited to DC to 200 MHz frequency but will handle +/- 200 V and 1 amp. Multiple switch points can be closed at once.

Single Pole Armature RF Relays -- Bi-directional mechanical relays. DC to 2.5 GHz. Tree switched so only one channel may be closed at a time.

Two Pole Armature Relays -- Bi-directional mechanical relays. DC to 200 MHz. For switching balanced lines or 100 ohm pairs.

Low Leakage Reed Relays -- Used to measure extremely low currents (down to 100 Femto amps) or high resistances (Terra Ohms). Withstands up to 1500 Volts.

Solid State RF Relays -- Very fast switching speeds and very long life expectancy. Limited lower frequency range and limited in power to about 24 dBm (1/4 watt).
