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 fi rst two digits de fi ne the year and the last two digits defi ne the week of the year (YYWW). Thus, 1032 identi fi es switches that passed through fi nal 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. 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 specifi ed, 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 speci fi ed 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, 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 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 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.
