CXM Series - Microwave and RF Switching Systems and Drivers

CXM Series -- this series is typically used for frequencies from DC to 40 GMHz. We use microwave relays, splitters, programmable attenuators and many other microwave components from the worlds most popular vendors to build standard or custom systems to your specifications. There are a large variety of 1x2 through 1x12 microwave relays available in Normally Open, Failsafe, Latching, Terminated or special configurations to suit your needs. Or simply buy the driver chassis and use it to control your own components. Since Cytec doesn"t build microwave components we can put the systems together with whatever parts you prefer and stand behind the warranty for you.

Normally Open relays (NO) require one drive per relay port and default off is no port closed. Latching (-L) relays require one drives per port but have no OFF ( Normally Open) state.



CXM/6x1-NO-T Relay CXM Terminated Multi-throw Relay drawing

CXM/3x1 to CXM/10x1 Terminated Microwave Relays (SP3T to SP10T)

CXM/3x1 to 10x1-NO-T-SMA Microwave Relays are Normally Open (NO) in the OFF state. Only one port can be on at a time. Larger configurations can be built by connecting the common port of multiple relays to another relay in series. These relays are terminated to 50 ohms at each port except the common when in the off state.

Terminated relays are used for multiple purposes. The main purpose is for systems that require the output of the device connected to the relay be terminated in 50 ohms to maintain charactoristic impedance, such as splitters. Sometimes it is simply a good pratice to terminate the device to protect the output such as certain op amps. The other major reason is to provide slightly better isolation between ports since terminations take the signal to ground rather than act as an unterminated stub.

Typical Specifications-- !specications will vary by relay type and size!
Bandpass DC to 18 GHz
Insertion Loss 0.3 to 0.5 dB @1 GHz, 0.8 to 1.2 dB @ 18 GHz
VSWR 1.2:1 to 1.3:1 @ 1 GHz, 1.5:1 to 1.8:1 @ 18 GHz
Isolation -85 dB @ 1 GHz, -65 dB @ 18 GHz
Termination Power 2 Watts max

Options:

  • Latching or pulse latching
  • 26.5 or 40 GHz extended bandpass and specifications

Normally Open relays (NO) require one drive per relay port and default off is no port closed. Latching (-L) relays require one drives per port but have no OFF ( Normally Open) state.


Cytec does not manufacture microwave components but uses microwave relays and components from a variety of vendors including Ducommun, Radiall, RLC, Dowkey, Mini-Circuits, JFW, Keysight, RF-Lambda, and many, many others. We can custom build from your BOM without being locked into any specific brand.
