4.8 IEEE - Transmit Power Spectral Density (PSD) Mask

The IEEE standard 802.15.4 requires the transmitted spectral power to be less than the limits specified in Table 7.

Table 7. Transmit PSD Limits

Frequency Relative Limit Absolute Limit
|f – fc| > 3.5 MHz –20 dB –30 dBm

Figure 7 shows the transmitted PSD at TC = 25°C, VDD = 3.0 V and f = 2440 MHz, measured on the SimpleLink™ ZigBee® Network Range Extender Reference Design[3] with a 50 Ω load.
