The ADF7242 datasheet mentions that 3dBm output is present in IEEE 802.15.4-2006 mode, when operating under nominal mode.
Why does it indicate in figure 50 of the adf7242 datasheet, that the output maximum is approx. -6dBm, even when the device is in IEEE 802.15.4-2006 with output power = 3dBm.?
The signal in Figure 50 of the datasheet is a modulated signal. This means that the total power of 3 dBm is spread out to the entire bandwidth.
Thanks for the response. That confirms a fair bit.
The figure 50 shows, a peak output of approx. -7dBm. That's nearly 10dB reduction due to spreading. Is that correct to assume?
Transmitting the carrier signal only would result to the maximum of 3 dBm output at the center frequency. But in the case of figure 50, a modulated signal was transmitted. If you get the total power across the entire bandwidth, you would arrive with 3 dBm.
