Application note
Using the SPIRIT1 transceiver under ARIB STD-T108 in the
920 MHz band
By Placido De Vita
Introduction
SPIRIT1 is a very low power RF transceiver, intended for RF wireless applications in the
sub-1 GHz band. It is designed to operate both in the license-free ISM and SRD frequency
bands at 169, 315, 433, 868, 915 and 920 MHz.
The Japanese Association of Radio Industries and Businesses (ARIB) was established in
response to several trends such as the growing internationalization of telecommunications,
the convergence of telecommunications and broadcasting and the need for promotion of
radio-related industries. The ARIB organism defines the basic technical requirements for
standard specifications of radio equipment.
This application note outlines the expected performance when using the Spirit1 under ARIB
STD-T108 (see References on page 33) in the 920 MHz band. For details on the regulatory
limits in the 920 MHz frequency band, please refer to the ARIB STD-T108 regulation in
References on page 33.
