Optimize Your RF-Testing with Dow-Key's® New High Repeatability RF Switch.

New Dow-Key® Reliant Switch™

RF and wireless devices are equipped with many signal paths between input and output ports that need to undergo rigorous and complex testing. Therefore the use of coaxial switches is essential, allowing the user to easily switch between I/O ports and avoiding the cumbersome task of having to disconnect and re-connect RF cables. Repeatability between port-to-port testing and repeated tests across different DUTs is critical; making that the life of a RF switch and its reliability crucial.

Dow-Key® Microwave designed the Reliant Switch™ for the ATE market to be used in testing DUT (devices under test) e.g. Systems on Chip (SoC) or 4G/LTE wireless signals during characterization, validation and production testing.

“Our Reliant Switch™ is a simple solution with high repeatability,” said Dow-Key® Application Engineer, Victor Crampton. “It is a must for automated testing.”

Dow-Key’s® new Reliant Switch™ guarantees insertion loss repeatability of 0.03 dB from DC to 26.5 GHz. It is a one-by-six (1x6) bidirectional coaxial switch with a wide operating frequency range extending from DC to 26.5GHz. The switch can operate both in break-before-make or make-before-break applications and has a fast switching speed of 15 ms and an extended life cycle where each position can switch a minimum of 5-Million cycles. The Reliant Switch™ offers a variety of control options including +24Vdc coil voltage, TTL discrete logic and CAN bus.
