A Solid-state, 1 to 2 GHz, 1 kW Amplifier

Until recently, traveling wave tube (TWT) technology was the only technology capable of meeting the bandwidth and power requirements of high power L-band applications such as power testing radar components and for military/automotive RF immunity testing. Solid-state technology can, however, offer key performance advantages over TWT technology, particularly with...

Millimeter-wave Satellite Remote Sensing

When the Hubble Satellite was launched in 1990, the joke was that it was the third best optical satellite in space, but that the two better ones were pointed in the opposite direction. While it is still true today that more satellites are looking downward than upward, satellites are...

Experimental Investigation of a Power Divider Based on Microstrip and Metamaterials with L-C Lumped-elements

One-dimensional metamaterials, using L-C lumped-elements, have a broad left-handed passband, with anti-parallel phase and group velocities. Power dividers, with symmetric and asymmetric structures, are proposed. They are composed of conventional micros...
Metamaterials ,1,2 with simultaneous negative permittivity and permeability, are promising materials for new types of microwave components. In metamaterials, the waves are propagating with anti-parallel phase and group velocities, as demonstrated by backward waves. 3 Recently, an extended transmission-line approach to metamaterials, low loss and broadband structures was proposed...

Broadband Tactical Communications Antennas

Military tactical communications require transportable radio systems that can be set up quickly in the field, under difficult conditions, to establish communication links. These radio systems are mounted in tactical operation centers (TOC), vehicles and shelters. Legacy antennas used in these systems operate primarily in the VHF or UHF...
