The combination of piezoelectrics and microelectromechanical systems (MEMS) can result in devices with a wide range of applications, including resonators, energy harvesters, and various sensors. Currently, improvement of MEMS devices designed to operate in the radio-frequency (RF) regime has been of particular interest due to the devices’ use in both commercial and military satellites and aerospace systems. The work presented characterizes and analyzes new designs for various RF MEMS devices produced at the US Army Research Laboratory. Their integration to a proposed mobile RF wireless communication system was investigated by developing a proof-of-concept demonstration of the proposed system.
The RF circuitry of the proposed system consists of various RF MEMS switches and filters. A customized smartphone modification was used to demonstrate the functionality of the RF circuitry and directly compare the size/weight/performance of the MEMS devices to commercial off-the-shelf components.

RF Cafe: X-Microwave Prototyping System

In case you don’t already know, a grown-up’s version of the much-ballyhooed littleBits electronics building block system is available. Instead of assembling snap-together functional blocks for making LEDs flash or robotic carts, X-Microwave’s system provides a relatively simple and inexpensive venue for designing and building RF and microwave circuits based on a selection of component blocks for frequencies ranging from hundreds of kHz to tens of GHz.
