抄録

A 0.8-5.2GHz broad-band quadrature mixer for SDR (Software Designed Radio) direct conversion receivers has been developed using 0.35μm SiGe BiCMOS process. The quadrature mixer employs a high speed static frequency divider for a 90deg LO power divider and broad-band SiGe HBT unit mixers. High speed operation of the static frequency divider is realized by adding 2-stage emitter follower to its output section. The fabricated quadrature mixer achieves an EVM of 3.1%rms for W-CDMA signals at 0.8GHz and an EVM of 2.1%rms for W-LAN (IEEE 802.11a) signals at 5.2GHz, respectively. It also has constant conversion gain over the wide base-band frequency range upto 500MHz at RF frequency of 0.8GHz.
