(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 contacts linked to the actuator. they can be wired to digital input lines, status lights, or interlocks. unless otherwise speci ed, the maximum indicator contact rating is 30 vdc, 50 ma, or 1.5 watts into a resistive load. internal termination unselected ports are internally terminated to a matched load. the load is 50 resistive device. the max rf power rating is 2 watts cw. without the internal termination option, the unselected ports are open circuits. 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 ed in db below the input power level. 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 elds. neighboring ferrous materials should be permitted no closer than 0.5 inches and adjacent external magnetic elds should be limited to a ux density of less than 5 gauss. glossary i a [1 + .00385 (t-20)] where: i t = actuator current at temperature, t i a = room temperature actuator current C see data sheet t = temperature of interest in c i t = carrier frequency 1 carrier frequency 2 pim 3rd order frequency pim 5th order fre- quency 870 mhz 893 mhz 847 mhz 824 mhz 3rd order intermodulation 5th order intermodulation spdt ?91 dbm ?110 dbm ?134 dbc ?153 dbc 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.
