A 40-80-Ghz Mhemt Single-Pole-Double-Throw Switch Using Traveling Wave Concept
Macau（2008）
Abstract
This paper presents a 40-80-GHz SPDT switch fabricated in mHEMT process. The SPDT switch accomplished insertion loss lower than 2.4 dB and isolation better than 23 dB. Via holes were shared to compact the layout and the chip size of 1 x 1 mm2 is obtained. Table 1 summarizes recently reported performance of SPDT switches in GaAs HEMT process.
