work all parts i, ii and iii, do not leave any part unanswered,will give a big thumb. please give a detailed answer, need it forsubmission.
MODULE: RF SYSTEMS AND DESIGN.
(d) Given the following sub-system and component specifications. LNA G₁, P3 Component RF LNA Mixer Mixer G₂, P3 LO Gain/Loss 20dB -6dB P₁ = 1 1 + G₂P3 P IP3 22dBm (ref output) 13dBm (ref input) (i) Find the overall IP3 (ii) Derive an equation for the levels of 3rd order distortion in terms of the overall IP3. What will hence be the levels of 3rd order distortion at an output power level of -10dBm? (iii) If the output noise level is at -60dBm, what is the spurious free dynamic range?
