Hello team,
Regarding TRF370417 datasheet figure1(Output Power vs Baseband Voltage), Could you let me know if below my understanding correct?
A case of BBIP-BBIN and BBQP-BBQN are moving on circle with radius of 0.1V with 50kHz(below graph) means VBB=0.1V. And in this case, output power is about -3dBm, according to figure 1.
Best regards,
Hi Sato-san,
You have the concept correct. The datasheet figure 1 is specifying RMS input voltage level, not peak. The circle that you are drawing is referenced to the peak I or Q voltage. In theory, there are sine/cosine waves in the Z axis serves as time, and the RMS level of the sine/cosine wave is the x -axis of the Figure 1.
Hello Kang-san,
According to Figure1, output power is about -3dBm in case of VBB is 0.1V.
What Vpp as BBIP will represent the VBB=0.1V?
Please see attached.
Best regards,
Hello Sato-san,
As the input source is a sine wave, you can follow the standard Vrms to Vpp conversion.
