The HFA3128 is an ultra high frequency transistor array that is fabricated from Intersil Corporation’s complementary bipolar UHF-1 process. Each array consists of five dielectrically isolated ...

A team of astronomers and engineers at ASTRON, the Netherlands Institute for Radio Astronomy, has successfully detected correlated interferometric radio signals, called “fringes,” from the sky with ...

The HFA is an acoustic "window" used in conjunction with the high frequency sail array. The primary purpose of an HFA window is to provide an acoustically transparent interface to seawater from the ...

Eye on the sky More than 130 Square Kilometre Array dishes will be added to the existing 64 of the SKA-precursor telescope MeerKAT to form a mid-frequency instrument. (Courtesy: South African Radio ...

The notion of a phased array was initially articulated by Nobel Prize recipient K. F. Braun. Phased arrays have subsequently evolved into a formidable mechanism for wave manipulation. This assertion ...

A bold claim can now be made in radio astronomy: The most sensitive, widest-area, low-frequency radio map of the Milky Way has been produced, presenting an image of our galaxy well beyond anything ...

Researchers have taken a step toward developing a type of antenna array that could coat an airplane's wings, function as a skin patch transmitting signals to medical implants, or cover a room as ...
