Marubeni Chemix Corp. announced it will feature a new dielectric material that is now commercially available. This material is thermoplastic with low dielectric loss and adjustable dielectric constant for custom needs and is easy to process for mass production. Marubeni will also display the application example, which is a...

Holzworth Instrumentation announces the release of the HS1001A USB-controlled 1.024 GHz RF synthesizer. Typical phase noise performance is -130 dBc/Hz at 1 GHz (10 kHz offset) with harmonics below -30 dBc and spurious below -60 dBc. Other features include: DC-coupled AM/FM/PM and pulse modulation capabilities, frequency sweep, internal/external triggering...

Avago Technologies announced the world’s smallest RF amplifier. The company is a leading supplier of analog interface components for communications, industrial and consumer applications. With miniature 0402 package dimensions and no wirebonds, the innovative VMMK-2x03 amplifiers experience almost no signal loss and minimal parasitics. Its ultra-small size and fully...

I. Introduction An antenna beam scanner which uses the principle of phasing for beam steering a linear array has been designed. Essentially it is a slow wave helical structure with a coupled non-contracting outer helix. The directionally coupled outer helix can be varied mechanically along the axis of the...

REMEC Defense and Space (a subsidiary of Cobham Defense Electronic Systems) has received notice by ATK of another successful milestone test of the Advanced Anti Radiation Guided Missile (AARGM) at China Lake, CA. The missile was launched off-axis from low altitude from an F/A-18C hornet aircraft and was able...

Lockheed Martin announced that it has achieved a major integrated test milestone on the first Space-based Infrared System (SBIRS) geosynchronous orbit (GEO-1) spacecraft that enables the start of environmental testing in preparation for launch in 2009. The GEO-1 satellite, designed to provide new missile detection and surveillance capabilities for...

Raytheon Co. is developing transmit-receive modules based on the advanced semiconductor gallium nitride (GaN) for use in future radar upgrades. “This transmit-receive module demonstration and parallel reliability testing show that GaN will soon be ready to take over where increased power and advanced capabilities are needed,” said Mark Russell,...

This article presents the design approach and test results of a X-/Ku-band 4-bit compact GaAs MMIC phase shifter developed for broadband applications. The phase shifter design is based on choosing an optimum topology for each bit, yielding compact size and low insertion loss. It also has on-chip integrated digital...

Scientists and engineers from around the world recently met in Australia to begin the preparatory phase for the biggest project ever undertaken in radio astronomy. The international Square Kilometre Array (SKA) will be 50 times more sensitive than any existing facility and will probe some of the biggest questions...

The European Space Agency and Astrium have signed a €195 M contract to provide the first Sentinel-2 earth observation satellite, devoted to monitoring the land environment, as part of the European Global Monitoring for Environment and Security (GMES) programme. As prime contractor, Astrium is responsible for the design, development...
