The High Frequency Structure Simulator (HFSS™) is a software tool for 3D full-wave electromagnetic field simulation. HFSS provides E- and H-fields, currents, S-parameters, and near and far radiated field results. Intrinsic to this engineering design tool is an automated solution process where users are only required to specify geometry,...

It goes without saying that components and sub-assemblies supporting today’s defense equipment, such as military radio receivers and counter-IED solutions, must be rugged, light and reliable. Increasingly critical, however, are a host of beyond-requisite demands that reflect today’s new military procurement and combat realities. One example is the dictum...

Sustained growth in wireless communications and greater demands for bandwidth place tremendous pressure on component manufacturers to provide high performance, surface-mount technology (SMT) packaged products. The market is seeking low-cost, SMT components for high volume printed circuit board (PCB) assembly flow, particularly for applications such as point-to-point (PTP) digital...

LINC2 Filter Pro Software Release ACS has recently released a new version of its LINC2 filter synthesis software. LINC2 Filter Pro version 1.18 adds new capabilities for exporting design and analysis data to other programs. This new version can send filter analysis data, including frequency response data, to Excel...

Power Divider Model PD0218-S2 is a two-way Wilkinson power divider that was just released and covers most military and EW bands from 2 to 18 GHz. These power dividers are available in octave and multi-octave bandwidths and are available from Aeroflex/Inmet stock. The designs are based on an industry...

RF Bulk Acoustic Wave Filters for Communications Ken-ya Hashimoto, Editor RF-BAW devices employing a piezoelectric thin membrane were proposed in 1980. Although their excellent performance was well recognized, the majority of engineers believed that their applicability was limited due to extremely tight requirements given to device fabrication. However, RF-BAW...

Passive Components Download the Puzzler Download the Puzzler (PDF) Across 5 A circuit that is designed to propagate signals of a desired frequency or frequency interval and to reject all other signals 7 Frequency-dependent impedance that is capable of storing but not dissipating energy 9 A component that transfers...

Raytheon Co. has received an $81.1 M US Navy contract for the AN/AQS-22 Airborne Low Frequency Sonar (ALFS), the primary undersea warfare sensor for the Navy's MH-60R multi-mission helicopter. "ALFS advances the capabilities of the Navy's anti-submarine warfare mission, giving the fleet an unfair advantage over enemy submarines," said...

The ZigBee® Alliance, a global ecosystem of companies creating wireless solutions for use in energy management, commercial and consumer applications, congratulates its members who were selected to receive funding for their Smart Grid efforts as part of the United States American Reinvestment and Recovery Act. ZigBee Alliance members received...
