very low power consumption in mixer?

Hello,
i wanna ask about consumption in mixer based on Schottky diode.
When we have :
VDC=0V (0 V bias for diode),
RF Power : 0dBm
and LO power=10dBm

can we say that the designed mixer has a very low power consumption ?

If no, when can we say that ?

or RF and LO powers must be negative value to say that mixer is ...?

Thank you in advance,

It all depends upon the total system power. Since mixers are usually the highest IMD contribution part of a system, this is no place to be stingy with power.

If i have understood we can not say for mixers are low power consumption or no ?
but i have seen in many paper they talk on mixers where they say that the mixers works with a very low power...!

What do you can say about that ?

Thanks in advance

is it low power LO?

i guess so, becoz earlier designs were with out LO amplifier.

the LO is 10dBm
what do you think ? is it high ?

It is OK, depend on requirement, even zero or 4dBm LO powered mixers are available now.

For the same functionality earlier designs requires near 20dBm powers.

yeah but i think we can not say that mixer is less or low power consumption!

since, other mixer can give a good performance with very low LO power such -3 dBm..
