Vericinin ikinci harmoniğine kadar bastırılmalıdır ki bu alıcı
en az 45 dB bastırılmalıdır.
if system linear → a_1A
if A_IIP3 → more linear System.
Compute IIP3 of the amplifier such that IM3 product falling at ω_1 ( → A_o,IM3 ??) is 20 dB below the desired signal ? ( → A_o,S )
Cascaded Nonlinear Stages
2. amplifier linearlığının ilkinden daha iyi olmalıdır.
