Test signal of CW in NXP datasheet....absolute peak power or RMS power?

时间:04-05 整理:3721RD 点击:
In NXP datasheets, it specifies test signals as CW, 2-tone or WCDMA.

For the CW test signal, is this an absolute peak power, or an RMS power?

For CW-2tones, it should generally be peak value unless it's been mentioned/remarked.

Thanks for the response. In that case, during MWO simulation where the PORT1 1-Tone or 2-Tones HB sources are defined as RMS Power (do you agree?), then the CW input power from datasheet should be divided by 2, as an input to the MWO's HB Ports, right? Example from datasheet CW-input is 20dBm,then it becomes 23dBm as my input for say 1-Tone HB source in MWO.

Simulator sources have peak value,not rms.

I'm not sure about that. How do you prove that it is an absolute peak power?

I tried to do a simple simulation test in MWO using a 1Tone HB 40dBm source at Zsource=50-ohm and a load of 50-ohms.
I put I_meter and V_meter in between and plotted V(t) and I(t).
My Vpeak=31.62 and Ipeak=0.6325. Then my Ppeak= 20W or 43dBm. Prms=Ppeak/2= 10W or 40dBm...Hence I thought that based on this, the 40dBm 1Tone HB source is defined as an RMS power.

Otherwise, please further explain why it is a peak value...Thanks
