DESCRIPTION
CCR-33M
Commercial Latching SPDT, DC-3GHz
CR-33M
Elite Latching 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 latching 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.

Latching SPDT Coaxial Switch
GLOSSARY
Actuator
An actuator is the electromechanical mechanism that
transfers the RF contacts from one position to another upon
DC command.
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.
Arc Suppression Diode
A diode is connected in parallel with the coil. This diode
limits the “reverse EMF spike” generated when the coil deenergizes to 0.7 volts. The diode cathode is connected to
the positive side of the coil and the anode is connected to
the negative side.
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.
Date Code
All switches are marked with either a unique serial number
or a date code. Date codes are in accordance with MILSTD-1285 Paragraph 5.2.5 and consist of four digits.
The first two digits define the year and the last two digits
define the week of the year (YYWW). Thus, 1032 identifies
switches that passed through final inspection during the
32nd week of 2010.
Latching
A latching switch remains in the selected position whether
or not voltage is maintained. This can be accomplished
with either a magnetic or mechanical latching mechanism.
Performance Parameters vs Frequency
Generally speaking, the RF performance of coaxial switches
is frequency dependent. With increasing frequency, 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
operating temperature of the switch and the actuator drive
current. For switches operating at 28 VDC, the approximate
actuator drive current at temperature, T, can be calculated
using the equation:
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
contacts linked to the actuator. They can be wired to digital
input lines, status lights, or interlocks. Unless otherwise
specified, the maximum 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
connector of an unconnected RF channel as referenced to
the power at the input connector. It is specified in dB below
the input power level.
Self-Cutoff
The self-cutoff option disables the actuator current on
completion of actuation. Either a series contact (linked
to the actuator) or an IC driver circuit provides the current
cutoff. This option results in minimum power consumption
by the RF switch. Cutthroat is another name used in the
industry for this option. Pulse latching is a term used to
describe a switch without this feature.
SPDT Switch
A single-pole double-throw, bi-directional switch that can
be used as having one input and two outputs or two 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 with the completion of the switch transfer,

IT =
IA
[1 + .00385 (T-20)]
Where:
IT = Actuator current at temperature, T
IA = Room temperature actuator current –
see data sheet
T = Temperature of interest in °C
Magnetic Sensitivity
An electro-mechanical switch can be sensitive to ferrous
materials and external magnetic fields. Neighboring ferrous
materials should be permitted no closer than 0.5 inches and
adjacent external magnetic fields should be limited to a flux
density of less than 5 Gauss.
SPECIAL FEATURE
Switching High-Power or Highly Sensitive Signals
Ensure the most linear response with the best galvanically
matched contact system in the industry. Extremely low
passive intermodulation is standard on all of our switches.
