Panasonic Develops Millimeter Wave Transceiver Chipset with Built-In Self-Calibration for Mobile Devices
OSAKA, Japan--(BUSINESS WIRE)-- 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.
- Incorporates built-in self-calibration to compensate for performance errors in millimeter wave wireless circuits.
- Employs signal processing circuits which equalize the distorted received signal with more than 50% power reduction compared to the conventional approach.
- 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 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 20th. Fast File Transfer Demo has also been given at Industrial Demo Session at the conference on the same day.
