MEMS consumption in mobile handsets reached $157 M in 2005 and by 2010, consumption will exceed $1 B, reports In-Stat. In addition to the microphones and bulk acoustic resonators that have dominated the MEMS market to date, there are emerging opportunities for inertial sensors (principally accelerometers) and several types...

Radio frequency identification (RFID) has become and will continue to be very important in the area of automated identification. With the current emerging RFID technology, it is now possible to have an under-the-skin ATM/credit card or to pay up for a trolley full of goods by pushing across an...

Friday the 13 th of December 1996 was a lucky day. Daylight, such as it was, found me traveling south from Syracuse on Route 81 in a cold windy rain. I was going to visit an old friend from Cornell, L. Pearce Williams, Professor Emeritus, History of Science and...

For the effective use of the available frequency spectrums, the channels of conventional communications satellite systems are allocated contiguously in frequency. Each channel is filtered by a channel filter with high frequency selectivity, amplified by a high power amplifier and transmitted to the ground through a single beam. Modern...

Rapidly growing wireless systems call for low loss filters with special requirements such as a suppressed second harmonic and a wide stop band region. Although conventional parallel coupled-line filters have many salient features, 1 their spurious response at 2f o make them unsuitable for modern day wireless systems. This...

In the RF and wireless industries, system performance requirements seem to expand almost daily. These systems continue to encompass more and more of today’s broad-reaching technologies. Engineers working in this environment are often tasked with designs that must combine and distribute RF signals from multiple input devices while, at...

Military Brochure The revised military brochure from AR Worldwide Modular RF features a family of booster amplifiers for tactical military radios that covers 30 to 512 MHz and 12 to 40 W. The family features several versions including manpack or vehicular mounted, manual or automatic band switching and a...

Space/Flight Qualified Low Noise Amplifiers These low noise amplifiers are designed, manufactured, tested and screened to be extremely reliable and rugged for space or flight applications. Screening options include MIL-STD-883 and MIL-PRF-38534. In addition to the testing and standards that go into these amps, the company also provides complete...
