Integrated Frontends for Millimeterwave Applications Using III-V Technologies.

In order to reduce the manufacturing cost for future 60 GHz products, a high integration level is necessary. Recent results on mHEMT and pHEMT multifunctional receiver/transmitters utilizing are reported. The building blocks for highly integrated millimeterwave front-end circuits based on III-V-technologies such as mixers, amplifiers, frequency multipliers, and VCOs are presented in this work. Balanced and single ended 7-28 GHz MMIC frequency multipliers are described and compared. Multifunctional MMICs utilizing single ended, subharmonically pumped, balanced and single sideband mixers are reported. Examples of multi-stage mHEMT and pHEMT wideband amplifier for example covering 43-64 GHz with a gain of 24 dB, a minimum noise figure of 2.5 dB and ripple of 2 dB are shown. [ABSTRACT FROM AUTHOR]
