RF and wireless devices are equipped with many signal paths between input and output ports that undergo rigorous and complex testing. Therefore the use of coaxial switches is essential, allowing the user to easily switch between I/O ports and avoid the cumbersome task of having to disconnect and re-connect RF cables. The quality and reliability of an RF switch are critical to ensure repeatability of port-to-port testing and multiple devices being tested.
Dow-Key® Microwave has designed the Reliant Switch?for the ATE market to be used in testing devices such as Systems on Chip (SoC) or 4G/LTE wireless signals during characterization, validation and production testing. It is a one-by-six bidirectional coaxial switch with a wide operating frequency range from DC to 26.5 GHz and a guaranteed insertion loss repeatability of 0.03 dB. Isolation ranges from 65 dB at the higher frequencies to 100 dB at the lower. Its third order intermodulation is typically -120 dBc (2 carriers at
20 W). Operating temperature is -25° to +75°C with power handling of 30 W at 4 GHz and 25°C.
The switch can operate in both break-before-make or make-before-break applications, 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 +24 VDC coil voltage, TTL discrete logic and CAN bus.
