1.25Gbps wireless Gigabit Ethernet link at 60GHz-band

A 1.25Gbps 60GHz-band full duplex wireless Gigabit Ethernet link has been developed. Direct ASK modulation and demodulation scheme is adopted for the 60GHz-band transceiver. CPW MMICs and planar filters are flip-chip mounted in TX and RX LTCC MCMs. The wireless Gigabit Ethernet link has a function to convert an optical fiber link to a wireless link seamlessly combining a 60GHz-band transceiver with a 1000 Base-SX optical in/out module. The size is 159/spl times/97/spl times/44mm/sup 3/.
