Series CCP-37S COAX SWITCHES Miniature DC–3 GHz Low PIM Latching TRANSFER Coaxial Switch PART NUMBER DESCRIPTION CCP-37S Commercial Latching TRANSFER, DC-3GHz, Low PIM These switches are designed to have extremely low passive intermodulation for use in narrow bandwidth communications applications. The CCP-37S is a long-life high performance transfer switch designed for use in 50 Ohms coaxial transmission lines operating over frequencies ranging from DC to 3 GHz. The switch is designed for minimum or where the contact paths are closed for long durations. This switch is provided with a magnetic latching actuator which is particularly desirable in applications where actuator power consumption must be kept to an absolute minimum. The latching type actuator requires less switching current than the failsafe type.

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. 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. 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. 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: 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. TRANSFER Switch A four-port switch consisting of two independent pairs of RF paths. These pairs are actuated simultaneously. This actuation is similar to that of a double-pole double-throw switch. Switching Time Switching time is the total interval beginning with the arrival of the leading edge of the command pulse at the switch DC © 2013 TELEDYNE RELAYS (800) 284-7007 • www.teledynecoax.com CCP-37S Page 5 CCP-37S\072013\Q3 Series CCP-37S Miniature DC–3 GHz Low PIM Latching TRANSFER Coaxial Switch COAX SWITCHES LATCHING CCP-37S PART NUMBER LIST PART NO. * PART NO. 1 CCP-37SXC 43 CCP-37SX0 2 CCP-37SXC-D 44 CCP-37SX0-D 3 CCP-37SXC-DM 45 CCP-37SX0-DM 4 CCP-37SXC-DMS 46 CCP-37SX0-DMS 5 CCP-37SXC-DR 47 CCP-37SX0-DR 6 CCP-37SXC-DRM 48 CCP-37SX0-DRM 7 CCP-37SXC-DRMS 49 CCP-37SX0-DRMS 8 CCP-37SXC-DRS 50 CCP-37SX0-DRS 9 CCP-37SXC-DS 51 CCP-37SX0-DS 10 CCP-37SXC-M 52 CCP-37SX0-M 11 CCP-37SXC-MS 53 CCP-37SX0-MS 12 CCP-37SXC-R 54 CCP-37SX0-R 13 CCP-37SXC-RM 55 CCP-37SX0-RM 14 CCP-37SXC-RMS 56 CCP-37SX0-RMS 15 CCP-37SXC-RS 57 CCP-37SX0-RS 16 CCP-37SXC-S 58 CCP-37SX0-S 17 CCP-37SXC-T 59 CCP-37SX0-T 18 CCP-37SXC-TM 60 CCP-37SX0-TM 19 CCP-37SXC-TMS 61 CCP-37SX0-TMS 20 CCP-37SXC-TS 62 CCP-37SX0-TS 21 CCP-37SXD 22 CCP-37SXD-M 23 CCP-37SXD-MS 24 CCP-37SXD-R 25 CCP-37SXD-RM 26 CCP-37SXD-RMS 27 CCP-37SXD-RS 28 CCP-37SXD-S 29 CCP-37SXD-T 30 CCP-37SXD-TM 31 CCP-37SXD-TMS 32 CCP-37SXE 33 CCP-37SXE-M 34 CCP-37SXE-MS 35 CCP-37SXE-R 36 CCP-37SXE-RM 37 CCP-37SXE-RMS 38 CCP-37SXE-RS 39 CCP-37SXE-S 40 CCP-37SXE-T 41 CCP-37SXE-TM 42 CCP-37SXE-TMS X = 6 (28Vdc), 7 (15Vdc), 8 (12Vdc) and 9 (24Vdc) CCP-37SPage 6 SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE © 2013 TELEDYNE COAX SWITCHES CCP-37S\072013\Q3
