Newly developed chip sets for 60 GHz radio communication systems

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 realized at Chalmers University are reported. Multifunctional MMICs utilizing single ended, subharmonically pumped, balanced and single sideband mixers are reported. Other chipsets for additional applications such as radiometers are reported as well. Most recently, a 220 GHz integrated receiver utilizing mHEMT technology was demonstrated.
