The Search For 5G mmWave Filters


Cellular telephone technology takes advantage of a large number of frequency bands to provide ever-increasing bandwidth for mobile use. Each of those bands needs a filter to keep its signals separate from other bands, but the filter technologies in current use for cellphones may not scale up to the full millimeter-wave (mmWave) range planned for 5G. “MmWave will happen,” said Mike Eddy, ... » read more

Challenges Grow For 5G Packages And Modules


The shift to 5G wireless networks is driving a need for new IC packages and modules in smartphones and other systems, but this move is turning out to be harder than it looks. For one thing, the IC packages and RF modules for 5G phones are more complex and expensive than today's devices, and that gap will grow significantly in the second phase of 5G. In addition, 5G devices will require an as... » read more

Toward Better Acoustic Resonators


After some lively conversations with the top researchers in MEMS acoustic resonators during the 2014 Sensors and Actuators Workshop (familiarly known to the MEMS community as “Hilton Head”), we set to work on a simulation solution to better serve researchers and commercial designers. Acoustic resonators for RF filtering have received a lot of attention in the past few years as the number... » read more
