Title: circuit engineer vs system level engineer
Post by NTR on Dec 19^th, 2011, 5:20am

Hi,
can any one explain what to be extracted from system level simulations of RF front end(LNA,mixer) .what kind of parameters will be expected by circuit designer from guy doing system level simulation.

Thank you for your time

hello,
from the system level specification you will have derive what is total NF, linearity and etc requirements, then you have to decide how you have to budget among LNA, MIXER, another blocks. Please read some basic RF book, probably you get all system level specifications in the following book

VLSI for Wireless Communication by Bosco Leung
Thanks,
Raj.

noise
linearity
spectral rejection of out of bad
gain
bandwidth
min-max signal amplitudes

min -max tolerances on all the above.

Probably forgetting something, but thats the short list
