Terminated Multi-Position Coaxial Switches (7 to 12 Position)
RLC Electronics’ Terminated 7-12 Multi-Position Coaxial Switch line provides proven reliability, long life and outstanding electrical performance. and features extremely low insertion loss and VSWR over the entire DC-18 GHz range, while maintaining high isolation. Standard RF power rating is 2 watts cw limited by the termination.

Power Rating, RF Cold Switching: 2 watts average Impedance: 50 Ohms Operating Power 25C: (Failsafe):
(Latching): “N/A” for 11-12 position. 12Vdc at 480mA (nominal), 28Vdc at 280 mA (nominal), Cutthroat circuitry (standard), recovery time 100ms (nominal) |
Connectors, RF: SMA Female Life: 1,000,000 operations. Switching Time: 25 mS Max. (failsafe) 125 ms (latching) Weight: 30 oz. 17 oz for 11-12 position Environmental Conditions: MIL-DTL-3928 Operating Mode: Failsafe/Latching/Manual (11-12 position only) Switching Sequence: Break before make. |
To designate the switch desired use:
1: “7”, “8”, “9”, “10”, “11”, “12” throw operation 2: “A” for 115 Vac, “D” for 28 Vdc or “H” for 12 Vdc 3: “I” for indicators. 4: “L” for Latching cutthroat. “N/A” for 11-12 position |
5: “TL” for TTL Driver ARCN for arc suppression diodes, common negative ARCP for arc suppression diodes, common positive Note: “T” automatically comes with suppression diodes. |
Example: STR-10-D is a SP-10T, 28 Vdc, Terminated, failsafe switch
