CXM COAXIAL MICROWAVE SWITCHES
Standard CXM Switches are 50 ohm, bi-directional, failsafe, Normally Open switches with a bandpass of
DC to 18 GHz. Microwave switches from 1x2 to 1x12 are available, and SMA connectors are standard.
OPTIONAL FEATURES INCLUDE: Failsafe default to Port 0 closed, latching actuators, BNC, TNC or N
Connectors, unused input ports terminated to 50 ohms and higher frequency or power handling capacity.
All options are not available on all models; contact one of our expert Sales Engineers for more information.

SWITCH MODULES SPECIFICATIONS
Microwave Switch specications vary depending on the options
selected. The following are typical:
Specications are for switches only. Cabling or connector
options may decrease some ratings. Call for specications
on assembled systems.
1 GHz 18 GHz
Insertion Loss 0.3 dB 0.8 dB
Isolation -80 dB -60 dB
VSWR <1.2:1 <1.5:1
Switching Time <15 ms <15 ms
RF Power, SMAs * 150 W 40 W
RF Power, Type N ** 300 W 90 W at 14 GHz
Notes:
* RF Power is CW cold switching at frequency indicated.
** Type N Connectors rated to 12 GHz only.

CXM TRANSFER SWITCH
Transfer Switches have four ports and
two switch postions. Postion 1 connects
Ports J1 to J4 and J2 to J3. Postion 2
connects J1 to J2 and Ports J3 to J4.
Options include different connectors
and frequencies to 40 GHz. See Fig. 3.
CXM/8X1-NO & CXM/10X1-NO
SWITCH MODULES
Are SP8T and SP10T congurations.
Different connectors are optionally
availalble.
CXM/6X1-NO SWITCH
Same as the CXM/4x1, but in a SP6T
conguration. The same options are
available.
CXM/2x1-F (Form C )
Is a SPDT microwave switch that de-
faults to its NC position. Options include
connector type, higher RF power han-
dling abiliy, unused port termination and
latching actuators.
CXM/4X1-NO SWITCH
Is a Single Pole 4 -Throw Normally Open
microwave switch. Options include con-
nector type, higher RF power, latching
actuators, failsafe operation, termina-
tions and frequencies to 40 GHz.
CXM TERMINATED SWITCHES
Self-terminating Microwave Switches
connnect all unused input port to ground
via 50 ohm terminations. Available with
all multipostion switches from CXM/2x1-T
to CXM/10-T. Terminations can handle
2 watts CW. See Fig. 4 for a schematic
of a terminated CXM/2x1-T.
CXM/2X1-T-SMA (TERMINATED)
Is a SPDT Microwave Switch with both
inputs terminated to 50 ohms when not
switched. See Fig. 4. Options include
latching actuators and frequencies to
26.5 GHz.
Are Single Pole 4 Throw and SP6T with
non-switched inputs terminated to 50
ohms. Options include latching actuators
and frequences to 40 GHz.
CXM/4X1-T-SMA & CXM/6X1-T
CXM/8X1-T-SMA & CXM/10X1-T
Are SP8T and SP10T with non-switched
inputs terminated to 50 ohms as shown in
Fig. 5. Options include latching actuators
and frequences to 40 GHz.
CONNECTOR OPTIONS
SMA Connectors are standard on all Microwave Switches rated
up to 26 GHz. Optional connectors include K Type rated at
DC to 40 GHz and N or TNC rated for higher power but lower
freqency applications. Not all connectors are available on
all switch types; for example, Terminated Switches are only
built with SMA or K Type. Please contact the factory for more
information.
LATCHING or FAILSAFE ACTUATORS
Microwave Switches with optional Latching Actuators remain
in their current switched positions until switched by the user
to another positon, even if power is removed. Switches with
optional Failsafe Actuators return to Port 0 closed when power
is removed.
CXM/10x1-NO-SMA
Cytec currently uses relays and microwave compo-
nents from multiple vendors. If you have a favorite
component manufacturer we'll be happy to use them.
