DC Power Consumption vs PAE

DC power consumption & PAE
Hi

What is the best way to measure the duration of the circuit? Let's assume there is no PAE vs Power consumption curve plot to see.

If people want to evaluate a duration of a circuit, can they only look at PAE without checking power consumption? or they need to look at both? or they look at power consumption based on certain PAE level?

because PAE is (ouptut power - input power)/(dc power consumption). high PAE may not necessary be low dc power consumption because PAE can be high if numerator high but denominator is even higher.

can we claim the table below saying [2] is a low power consumption design compared to [1]? Yet [1] has a higher PAE

[1] s11 & s22 no good makes it inefficient and at lower frequency ranges it burns much more power than [2] .

[1]
Poutput_1dB 6
Gain 18
S11 -5
S22 -5
Frequency Range 3-5 GHz
PAE 18
Power Consumption 22
(mW)


[2]
Poutput_1dB 2.32
Gain 15
S11 -10
S22 -8
Frequency Range 5-7GHz
PAE 12
Power Consumption 13mW

PAE calculation takes into account the power consumption.

Of course, but depends on the level of power consumption compared to the output power level.

If I want to compare [1] & [2] still

can i normalize [1] output delivered load to be the same as [2] and then compare the power consumption?

2.32/6 = x /22 , x=8.506 so [1] consume less power than [2]? compared to 13

or they actually cannot be compared regardless the frequency difference or there is a way still ?

tks

In most cases the input power used in PAE formula is neglected compared to output power (due to high gain of the amplifier).
So, never you get high PAE and high power consumption in the same time.
