Low power wireless sensors are receiving considerable attention due to their multiple applications in the commercial and military scenarios. Wireless networks of “power aware” smart sensors are being developed that are deployed and forgotten, 1 as well as the sensor elements themselves. Transducers integrated with radio transceivers and networking...

The fast growing demand for microwave communication technologies, such as broadband wireless and satellite communication, point-to-point radio links, as well as a variety of radar systems, brings up stringent requirements to modern microwave filter design techniques aimed at minimization of electromagnetic interference, cross talks and jamming. The most critical...

High efficiency microwave amplifiers with low supply voltages are required for mobile telecommunications services, such as GSM or DCS1800 systems. Theoretically, class-F power amplifiers (PA) can achieve 100 percent drain efficiency by maximally flattening the voltage and current waveforms of the active device. 1 By increasing the efficiency of...

As discussed in part one of this article, the measurement of very good VCOs at large frequency offsets is limited by the spectrum analyzer’s dynamic range. This limitation can be overcome by using carrier filtering and selective amplification of noise at the offset frequency of interest. The bandpass filter...

Both the IRIDIUM (LEO) and Odyssey (MEO) mobile satellite systems use constellations to provide worldwide continuous coverage. Each satellite in the constellation produces antenna beams covering wide areas. However, because the coverage areas are large, and the users in a coverage area may exceed the capacity of a single...

Ultra-high Speed Attenuator The model ADVAN-218-15DD options HS25NS and 5B is a 2 to 18 GHz digitally variable attenuator. This model offers a dynamic range of 15 dB in 0.5 dB steps and uses 5 bit binary control. The switching speed is 15 ns maximum, 6 ns typical. The...

Test Software The InterLab® program is available in three different versions including InterLab Solo, Professional (two to five users) and Enterprise (over five users). With InterLab, only one tool is necessary to make engineering processes, test and measurement procedures and information management processes more efficient. Measurement and test results...

Raytheon’s ASQ-228 ATFLIR targeting pod is now deployed with two F/A-18C Hornet squadrons onboard the USS John F. Kennedy (CVN 67). Delivered to the Navy just weeks before deployment, these ATFLIR pods successfully completed numerous missions during July — without missing a single sortie. “Only ATFLIR is designed and...
