hi,
can anybody provide suggestion on low-gain mode of LNA?
normally, how does low-gain mode work for high linearity?
1) design two configuration, one for high gain, another for low gain, and switch between them
2) directly use the same configuration with different bias?
which way is better?
in (1) condition, for a common soruce LNA, will the switch degrade the linearity?
many thanks!
