Millimeter-Wave Communication Chips from Hitachi, Panasonic and Toshiba

Supplier News

Leading Japanese manufacturers Hitachi, Panasonic and Toshiba have introduced millimeter-wave communication chips for use in digital home electronics.

Hitachi, Panasonic and Toshiba recently announced their latest development of RF transceiver ICs in the 60GHz band.

All three Japanese manufacturers aim to create ultra-small millimeter-wave transceiver units with integrated antennas.

With a bandwidth of only 7GHz and utilising a 60GHz radio frequency spectrum, these millimeter-wave communication chips will enable high speed transfer rates of 1.5 Gigabits per second. This means that downloading a 640MB CD will take about 5 seconds or a 2-hour SD quality video will take about 9 seconds.

The market growth of the new technology is expected to rise with Panasonic, LG Electronics and other companies releasing AV equipment incorporating WirelessHD standard utilising SiBEAM chipsets.

Hitachi intends to make use of millimeter-wave communication chips in large screen TVs, Blu-ray disc recorders and other home entertainment products for the transfer of high-definition video streams between AV equipment.

A prototype CMOS receiver IC has been designed by Hitachi with module combination of the IC, an antenna and additional components to support data communication with 802.15.3c compliance.

This device was manufactured using 130nm CMOS technology with a VCO (voltage-controlled oscillator) integration, mixer and low-noise amplifier (LNO).

Panasonic’s use of their millimeter-wave transceiver modules is focused on applications in mobile phones, with the aim to single-chip the entire package using CMOS technology.

Toshiba plans to use millimeter-wave communication to construct completely cordless digital equipment.

Toshiba is developing single-chip RF transceivers, which utilise semi-conducting chip bonding wires as the actual antenna. The company is planning a single-chip solution using CMOS technology without the need for a dedicated antenna or any extra components.

The millimeter-wave communication products will be available from POSMarket.com.au .
