Analog Devices (ADI) has unveiled a new RF-MEMS switch technology which it says can replace electromechanical relays and mitigate their performance limitations in applications such as aerospace and defense, healthcare, and communications infrastructure equipment.

With the new MEMS technology, OEMs can significantly improve the accuracy and versatility of automatic test equipment (ATE) and other instrumentation tools to help their customers reduce testing costs, power and time to market.

“The new products ADGM1304 and ADGM1004 RF MEMS switches are 95 percent smaller, 30 times faster, 10 times more reliable, and use 10 times less power than conventional electromechanical relays”, the firm claims.

Unlike other switch alternatives such as solid-state relays, the new ADGM1304 and ADGM1004 are said to offer superior precision and RF performance from 0 Hz (DC) to 14 GHz.

By increasing cold-switching lifetime by a factor of 10 compared to electromechanical relays, the highly reliable ADGM1304 and ADGM1004 extend ATE system operating life and reducing costly downtime caused by relay failures.

Additionally, the extremely small height of these switch packages allow designers to surface-mount the devices on both sides of their ATE test boards to boost channel densities at reduced cost and without expanding equipment footprint.

In addition, an integrated charge pump removes the need for external drivers, further reducing ATE system size, while a multiplexer configuration simplifies the fan-out structure compared to DPDT relay designs.
