Re: The load of the LNA?
Yes, my LNA is a differential cascode one. The output I set is 10kohms to prevent the loading effect. Is that correct? Is the 10kohms load play the role of the buffer? Also, will the power taken by the buffer be considered as the power consumption of the LNA?
Another interesting things is that: if I put the load to 10koms, the gain is quite high, but the s21 is low. While if I put it to about 1Koms, the voltage gain is lowered, but s21 is increased, so I am confused, shall we consider s21 more or voltage gain more in the LNA? Thanks very much
