Dow-Key® Microwave has released SP6T and SPDT switches to the Reliant Switch™ family, giving the automated test equipment (ATE) industry the flexibility to choose between lifetime and cost without sacrificing performance.

The SP6T switch has an operating frequency range of DC to 26.5 GHz, guaranteed insertion loss repeatability of 0.03 dB across the full band and 100 dB isolation up to 12.4 GHz. The switch has 50 Ω, 2 W terminated ports and is offered with latching actuators, SMA connectors, optical position indicators and the option of a TTL interface. The SP6T switch is designed for an operating life of 5 million cycles.

Dow-Key’s SPDT and SPDT terminated coaxial switches also cover DC to 26.5 GHz and achieve the same insertion loss repeatability of 0.03 dB across the entire frequency range. They also have latching actuators, optical position indicators, SMA connectors and an optional TTL interface. However, these SPDT switches have an extended operating life of 10 million cycles.

Engineers performing component manufacturing and system integration face the challenges of reducing the cost of test while ensuring reliability over the life expectancy of the test system. Test reliability requires maintaining insertion loss repeatability between ports, to increase measurement accuracy and reduce the source of errors. A longer life expectancy keeps the cost of replacing RF switches to a minimum and reduces system downtime. Dow-Key Microwave’s Reliant Switch product line is economically priced to minimize budgetary concerns, while delivering excellent electrical and mechanical performance over a broad frequency range.
