Mini-Circuits Mechanical SPDT Switch, DC-18 GHz, SMA, TTL Control ZK-MSP2TA-18

Mini-Circuits’ ZK-MSP2TA-18 is an ultra-reliable electro-mechanical SPDT switch operating over a wide bandwidth from DC to 18 GHz with high isolation and low insertion loss. The switch is absorptive and fail-safe with a break before make configuration and lifetime of 5 million switching cycles when used within the noted specifications. All RF connections (SMA female) are conveniently grouped together on the front of the switch. Simple control via TTL voltage levels allows integration with a wide range of microcontroller, embedded or custom systems without the additional complexity of USB or Ethernet control from a PC. The TTL control input and +24V DC supply connections are accessed through a single 3-pin PCB header connector on the rear of the switch. An LED indicator is also included on the rear of the package to give a convenient visual read out of the current switch state. An LED light-pipe connector allows the indicator to be routed to wherever it is needed when the switch is integrated into a final product.
