PRODUCTION DATA

8.13 Zigbee - IEEE 802.15.4-2006 2.4 GHz (OQPSK DSSS1:8, 250 kbps) - TX

Measured on the CC26x1-P3EM-7XD24-PA24 reference design with T_c = 25 °C, V_DDS = 3.0 V, f_RF= 2440 MHz with
DC/DC enabled and high power PA connected to V_DDS unless otherwise noted.
All measurements are performed at the antenna input with a combined RX and TX path, except for high power PA which is measured at a dedicated antenna connection. All measurements are performed conducted.

(1) To ensure margins for passing FCC band edge requirements at 2483.5 MHz, a lower than maximum output-power setting or less than 100% duty cycle may be used when operating at 2480 MHz.

(2) To ensure margins for passing FCC band edge requirements at 2483.5 MHz, a lower than maximum output-power setting or less than 100% duty cycle may be used when operating at the upper 802.15.4 channel(s).

(3) To ensure margins for passing FCC requirements for harmonic emission, duty cycling may be required. The CC2651P3 LaunchPad reference design should also be reviewed as the filter provides higher attenuation of harmonics compared to the CC26x1-P3EM-7XD24-PA24 reference design.

(4) Measured on evaluation board as described in https://www.ti.com/lit/pdf/swra636.
