PART NUMBER DESCRIPTION
CCR-33M Commercial Failsafe SPDT, DC-3GHz
CR-33M Elite Failsafe SPDT, DC-3GHz
The CCR-33M/CR-33M is a broadband, SPDT, electromechanical, coaxial switch designed to switch
a microwave signal from a common input to either of two outputs. The characteristic impedance is 75
Ohms. The small switches incorporate mini-SMB connectors.
The CCR-33M/CR-33M series switch is offered with a failsafe actuator. This design is compatible with
the two most common mounting hole patterns. The CCR-33M/CR-33M series switch is interchangeable
with a variety of switches.

Failsafe SPDT Coaxial Switch COAX SWITCHES
Actuator
An actuator is the electromechanical mechanism that
transfers the RF contacts from one position to another upon
DC command.
Arc Suppression Diode
A diode is connected in parallel with the coil. This diode
limits t he “revers e EMF spike” gener ated wh en the c oi l de -
energizes to 0.7 volts. The diode cathode is connected to
the po sitive side of the c oil and the ano de is connected to
the negative side.
Date Code
All sw itch es are m ar ked with ei ther a uni que se ri al numbe r
or a date code. Date codes are in accordance with MIL-
STD-1285 Paragraph 5.2.5 and consist of four digits.
The fi rst two digits defi ne the year and the last two digits
defi ne the week of the year (YYWW). Thus, 1032 identifi es
switches that passed through fi nal inspection during the
32nd week of 2010.
Failsafe
A failsafe switch reverts to the default or failsafe position
when actuating voltage is removed. This is realized by a
return spring within the drive mechanism. This type of switch
require s th e continuous ap plicati on of operating voltage to
select and hold any position. (Multi-position switches are
normally open with no voltage applied).
Indicator
Indicators tell the system which position the switch is in.
Other names for indicators are telemetry contacts or tellback
circuit. Indicators are usually a set of internally mounted DC
co nt ac t s linked to th e ac tu ato r. They c an b e wi re d to di git a l
input lines, status lights, or interlocks. Unless otherwise
specifi ed, the ma ximum indicator contact rating is 30 Vdc,
50 mA, or 1.5 Watts into a resistive load.
Isolation
Isolation is the measure of the power level at the output
co nnecto r of an unco nnecte d RF chann el as referenc ed to
the power at the input co nnector. It is speci fi ed in dB be low
the input power level.
SPDT Switch
A single-pole double-throw, bi-directional switch that can
be used as having on e input and t wo out puts o r t wo inputs
and one output.
Switching Time
Switching time is the total interval beginning with the arrival
of the leading edge of the command pulse at the switch DC
input and ending w it h t h e comp let i on of t h e swi tc h t rans fer,
including contact bounce. It consists of three parts: (1)
inductive delay in the coil, (2) transfer time of the physical
movement of the contacts, and (3) the bounce time of the
RF contacts.
TTL Switch Driver Option
As a special option, switch drivers can be provided for both
failsafe and latching switches, which are compatible with
industry-standard low-power Schottky TTL circuits.
Performance Parameters vs Frequency
Generally speaking, the RF performance of coaxial switches
is frequency dependent. With increasing f requency, VSWR
and insertion loss increase while isolation decreases. All
data sheets specify these three parameters as “worst case”
at the highest operating frequency. If the switch is to be
used over a narrow frequency band, better performance
can be achieved.
Actuator Current vs Temperature
The resistance of the actuator coil varies as a function of
temperature. There is an inverse relationship between the
oper ating temperatur e of the switch and t he actuator dri ve
current. For switches operating at 28 VDC, the approximate
actuato r drive cur rent at temperat ure, T, can be c alculated
using the equation:
Magnetic Sensitivity
An electro-mechanical switch can be sensitive to ferrous
materials and external magnetic fi elds. Neighboring ferrous
materials should be permitted no closer than 0.5 inches and
adjacent external magnetic fi elds should be limited to a fl ux
density of less than 5 Gauss.
