Recent interest in the 60 GHz band for high data rate short range wireless links has led to the significant progress in the development of integrated circuits for RF front-ends. CMOS process technology is being widely discussed for low-cost, low power mm-wave radio systems applications. In this paper we discuss various CMOS based circuits which have been developed considering carefully all the aspects such as device characterizations, the circuit topology, the circuit layouts, integration on a lost packaging for high volume fabrication lowering the cost and opening huge commercial opportunities of millimeter wave technology in the consumer electronic market place in a fairly near future.
