Hi all,
thanks for your replies. Yes I know based on my modulation scheme the required BER at the ADC. Based on what I know of the IF blocks, I also estimated the IRN of the IF blocks at the mixer output, and from there I knew the required gain and NF of the LNA/Mixer stage.
My question was really that if the functions of voltage gain, low noise figure (LC networks can have 3 dB NF even on-chip) and input matching can be performed by an LC network, is there really a need for an LNA?
thanks, Aaron
