Series CCT-49K/CT-49K Internal 50Ω Termination DC-40 GHz Latching Multi-Throw Coaxial Switch COAX SWITCHES PART NUMBER DESCRIPTION CCT-49K Commercial Latching Multi-throw, DC-40 GHz CT-49K Elite Latching Multi-throw, DC-40GHz The CCT-49K/CT-49K is an Internally Terminated broadband, multi-throw, electromechanical coaxial switch designed to switch a microwave signal from a common input to any of 3, 4, 5, or 6 outputs. The characteristic impedance is 50 Ohms. Internal terminations provide an impedence match for the unselected ports. The switches are small using the popular connector spacing on a 1.062” dia. circle. Each position has an individual actuator mechanism allowing random position selection. This also minimizes switching time. The CCT-49K/CT-49K comes with a latching actuator. The latching switch remains in the last position selected when the switch is de-energized. STD dual command requires a reset pulse before a new selected position. A separate reset circuit allows all positions to be set to an open position. User must provide both reset (clear) and set (select new position) commands. Available with USB & Ethernet Control!

CCT-49K/CT-49K Internal 50Ω Termination DC-40 GHz Latching Multi-Throw Coaxial Switch GLOSSARY 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. DUAL PULSE SWITCHING COMMAND CHARACTERISTICS: 1. APPLIES FOR SINGLE-POLE MULTI-THROW LATCHING SWITCH ONLY. 2. MUST APPLY RESET PULSE FIRST (BREAK-BEFORE-MAKE). 3. RESET AND SET DEFINITIONS RESET: OPEN ALL RF PATHS (POSITIONS). SET: CLOSE THE SELECTED RF PATH (POSITION). 4. COMMAND PULSE TIMING: RESET PULSE SET PULSE V VOLTAGE PULSE (SEE NOTE 5) COAX SWITCHES 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: 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 O T1 T3 T2 T1 AND T2 = 30 mSEC MIN. T3 = 10 mSEC MIN. I1 I2 CURRENT PULSE (SEE NOTE 6) ON SWITCHING TIME (MONITOR RF CONTACT): T4 AND T5 = 20 mSEC MAX OFF T4 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. T5 5.
