  Panasonic Develops Millimeter Wave Transceiver Chipset with Built-In
  Self-Calibration for Mobile Devices

OSAKA, Japan -- February 19, 2013

Panasonic Corporation has developed technologies to reduce performance errors
and maximize the transistor performance in chips for multi-gigabit wireless
utilizing the 60GHz wireless band, which is expected to be the future of
high-speed wireless communication. The transceiver LSI also features an
integrated miniaturized module including an antenna, which contributes to the
realization of stable high speed wireless communication for mobile devices.

The chipset incorporates built-in self-calibration to compensate for
performance errors, improving the modulation accuracy more than 1.5 times.
This makes it possible to reduce the circuit design margin, leading to the
improvement of the stability of wireless communications with less than 1W
power consumption. By integrating the transceiver LSI into the miniaturized
module, the chipset can be implemented in mobile devices, enabling the easy
exchange of the rich content, such as high definition videos, among mobile
devices wirelessly.

The developed technology has the following features.

1.Incorporates built-in self-calibration to compensate for performance
    errors in millimeter wave wireless circuits.
2.Employs signal processing circuits which equalize the distorted received
    signal with more than 50% power reduction compared to the conventional
3.Integrates the transceiver LSI in the miniaturized module including the
    transmit antenna and the receive antenna (size: 10mm x 10mm).

This development is based on the following new technologies.

1.Built-in self-calibration for the transmitter and the receiver which
    reuses existing circuit blocks to minimize the chip area.
2.Unique low power frequency domain equalizer which significantly reduces
    circuit size by using a newly proposed signal processing algorithm.

Panasonic holds 48 Japanese patents and 46 overseas patents, including pending
applications, for this development.

This result was supported in part by the "research and development project for
expansion of radio spectrum resources" of The Ministry of Internal Affairs and
Communications, Japan. A part of this release has been presented at IEEE
International Solid-State Circuits Conference 2013 at San Francisco on
February 20^th. Fast File Transfer Demo has also been given at Industrial Demo
Session at the conference on the same day.
