The authors have demonsraed integrated receiver components addressing 26 GHz Local Mulipoint Disribution Services (LMDS) applications using a standard SiGe HBT MMIC process wih an layouted emiter width of 0.8 μm. Compact circuit layout and transistor strucure optimization are applied to a mature Si/SiGe technology, resulting in low-cost integrated circuits enabling consumer-oriented systems at 26 GHz. The integrated receiver components are a downconverter and a satic 2:1 divider. The downconverter IC consists of a preamplifier and a mixer with an IF buffer. The conversion gain is determined to be 24 dB for an intermediate frequency of 200 MHz, and the maximum frequency of operation for the divider is 28.2 GHz.
