CC2530 支持跳频吗?

我现在做一个简单的点对点通信,CC2530支持跳频吗?数据手册上没有讲到这类的内容

FCC Part 15.247 limits the output power to 1 W or +30 dBm when Direct Sequence Spread
Spectrum (DSSS) modulation or Frequency Hopping Spread Spectrum (FHSS) with at least
75 hop channels is used. The spectral density of digital modulation systems (not including
FHSS) shall not exceed 8 dBm/ 3 kHz. The minimum 6 dB bandwidth of such systems is 500
kHz. Since the CC2530 is an IEEE 802.15.4 compliant transceiver, it uses DSSS modulation.
The +30 dBm limit therefore apply for the CC2530 with the CC2591 combination

Thank you very much for though word. But I have some question for your answer.

The spectral density of digital modulation systems (not including FHSS) shall not exceed 8 dBm/ 3 kHz.

Did CC2530 limiting the output power ?

We know the CC2530 Support 16 channel for 802.15.4.Can we use though channel  achieve a simple frequency hopping?

Did You mean that frequency hooping need a narrow bandwidth to use all 75 hop.  In CC2530 U.G.  The registers MDMCTRL0-TX_FILTER can limit the output bandwidth. May I use it on my system without CC2591?  Can we use it in lab testing? 

We thank you for your time and we appreciate your feedback.
