Latching Multi-Throw 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 the
“reverse EMF spike” generated when the coil de-energizes 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.
Date Code
All switches are marked with either a unique serial number or a
date code. Date codes are in accordance with MIL-STD-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.
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.
Multi-Throw Latching Switch
A multi-throw switch is a switch with one input and three or more
output ports. The CCT-49K can switch a microwave signal to any
of 2,3,4,5 or 6 output from a single common input.
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, 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.
TD-Option
This option includes a decoder. The 3-bit parallel command is
decoded to internally select the appropriate position. See the logic
tables. The TD-Option increases the Vsw supply current demand
by 50mA max at 28Vdc and +20°C.
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:
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.
