CC2541 BLE Output power limits - CC2590 range extender

Other Parts Discussed in Thread: CC2541, CC2590

Hi,

my product will be sold in Europe and will have to meet the ETSI limits.

I'm reading the following AN:  http://www.ti.com/lit/an/swra422/swra422.pdf

The CC2590 amplifier is meant there to extend the range of the CC2541

QUESTION

---------------

I can't understand the following part:

"The CC2541 - CC2590 EM reference design has been tested for compliance with FCC P art 15.247. While it is not a formal certification, it does give a good representation of emissions with respect to compliance requirements. The FCC Part 15.247 compliance is generally a tougher requirement than ETSI compliance ( EN 300 328) due to the restricted bands of operation. There are however requirements with regards to ETSI compliance (EN 300 328) that prevents operation at maximum output power. The clause 4.3.2.2 Maximum Power Spectral Density requirement of EN 300 328 requires maximum +10 dBm/ 1 MHz. The final output power level will depend on the antenna used. BLE requires that the max power emitted by the DUT not exceed +10dBm EIRP 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 CC2541 is a Bluetooth ® low energy compliant transceiver, FCC classifies the system, as a digitally modulated system . The +30 dBm limit therefore applies to the CC2541 with the CC2590 combination. "

Can anybody briefly explain me if CC2541+CC2590 can output more than 10 dBm?

Thanks in advance,
