AN658 Si446X AND ARIB STD-T67 COMPLIANCE AT 426–429 MHZ
This application note demonstrates the compliance of Si446x (B0, B1, C0, C1, C2) RFICs with the regulatory requirements of ARIB STD-T67 (V1.1, dated November 30th 2005) in the 426/429 MHz band. Although other members and revisions of the Si446x family of chips may also be used to achieve compliance within this frequency band, the measurements within this document were taken with an Si4461-B0 RFIC on a 4461-TSC13D434 Direct Tie RF Test Card (see “7. Reference Design Schematic” ).
The Si4461-B0 chip was configured to transmit at +10 dBm output power by appropriate settings of the DDAC[6:0]field in the PA_PWR_LVL property 0x2201 and the OB[5:0] field in the PA_BIAS_CLKDUTY property 0x2202. Various data rates and deviations were chosen in order to comply with the permissible channel spacings and occupied bandwidths. The tests were performed at a supply voltage of VDD=3.3 V.
