摘要

Millimeter-wave broadband transceivers with data rates as high as 1.5Gbps have been developed on the unlicensed 60GHz-band. A direct ASK modulation and demodulation scheme is adopted for the 60GHz-band transceiver. The Traveling Wave Switch (TWSW) as an ASK modulator and an integrated HJFET data driver realizes ultra fast 60GHz-band modulation. To enable a highly producible and compact transceiver module, CPW MMICs and planar filters are flip-chip mounted in TX and RX LTCC MCMs, which are assembled on printed wiring boards using BGA connection. 1.25Gbps full duplex wireless Gigabit Ethernet transceivers having a function to convert a 1000BASE-SX optical fiber link seamlessly to a wireless link, a 1.485Gbps uncompressed HDTV wireless transmission system and so on have been commercialized.
