Ein kompaktes, koplanares W-Band Verstärker MMIC mit variabler Verstärkung und großem Variationsbereich, basierend auf dual-gate Transistoren mit hoher Elektronenbeweglichkeit
Abstract
A W-band variable gain amplifier MMIC with 37 dB gain at 94 GHz and a gain control range of over 70 dB has been developed. The circuit consists of four dualgate HEMT stages, using a 0.15 mu m AlGaAs /InGaAs/GaAs PM-HEMT technology. The chip was realized in coplanar technology and requires an area of only 1 x 3 mm2. The resulting power gain density is 12 dB/mm2 at 94 GHz.
