Panasonic Develops Millimeter Wave Transceiver Chipset with Built-In Self-Calibration for Mobile Devices
OSAKA, Japan --(Business Wire)--
Panasonic (News - Alert) 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.
Incorporates built-in self-calibration to compensate for performance
errors in millimeter wave wireless circuits.
Employs signal processing circuits which equaize the distorted
received signal with more than 50% power reduction compared to the
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.
Built-in self-calibration for the transmitter and the receiver which
reuses existing circuit blocks to minimize the chip area.
Unique low power frequency domain equalizer which significantly
reduces circuit size by using a newly proposed signal processing
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 (News - Alert) International Solid-State Circuits Conference
2013 at San Francisco on February 20th. Fast File Transfer
Demo has also been given at Industrial Demo Session at the conference on
the same day.
