Application note

Using the SPIRIT1 transceiver under the ARIB STD-T67

standard in the 426 MHz band

By Placido De Vita

Introduction

The 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 to promote radio

related industries. The scope of the ARIB organism is defined as the basic technical

requirements for standard specifications of radio equipment.

This application note outlines the expected performance when using the SPIRIT1 under the

ARIB STD-T67 [2] standard in the 426 MHz band. For details of regulatory limits in the 426

MHz frequency band, please refer to the ARIB STD-T67 standard [2].
