60 GHz OFDM Transceiver RF Frontend Design in SiGe BiCMOS

J. C. Scheytt et al.

Workshop "Recent Advances in 60 GHz Wireless System Architectures: Prospects and Challenges", IEEE Radio and Wireless Symposium 2010, New Orleans.

Abstract: OFDM modulation has been proposed for different 60 GHz Wireless LAN and PAN systems. In OFDM systems the sub-carrier signal-to-noise ratio is determined not only by the receiver SNR but to a large extend also by the transmitter non-linearity and the local oscillator phase noise. Most critical components for OFDM transceiver frontends are therefore PAs with a high P1dB as well as low-phase noise synthesizers. The talk presents two different 60 GHz transceiver frontend architectures for 1 Gbps and 2 to 6 Gbps transceivers as well as integrated transceiver frontend ICs. The transceiver RF frontends are implemented in a low-cost 0.25 µm BiCMOS technology. RFIC design and system modeling results wrt. RF impairments are shown and discussed. Furthermore basic requirements for a SiGe beamforming transceiver are discussed.
