From automotive to IoT

Xidas miniature electromagnetic RF/
microwave relay.

to avoid degrading the relay's lifetime. He
added that in addition to automated test,
the relays can serve in military/aerospace
test, telecommunications test, and consumer wireless test.
The relays' RF performance extends to 8
GHz, Dhillon said, and they have been designed to provide seamless transmission

throughout the signal path, avoiding
transmission losses from the relay to the
circuit board, thereby improving overall
switching system VSWR. He commented,
"Our relays become part of the RF stripline!" He added that the low-power devices are bistable latching relays that don't
require power to stay in an on or off state.

Gibson at VTI Instruments identified
trends for switching systems in the
automotive space. "With all the advances in automotive technology such
as advanced driver assistance systems
and autonomous vehicles, suppliers of
these systems to the automobile manufacturers will require RF switching in
their test systems," he said, adding that
cars will have multiple high-frequency
systems including lidar, microwave radar, Bluetooth, and Wi-Fi.
"With the increased integration of
modern devices in the face of IoT, manufacturers have to perform a wider variety of tests, often involving different
instruments," said Campbell at Keysight.
"Switches give them a way to streamline
these measurements by routing multiple
instruments to one DUT, minimizing
the number of connections they have
to make."
