Abstract :
The most stringent second-order intermodulation intercept point (IIP2) requirement is given by single-tone S2 test patterns: the maximum interferer level for a portable receiver (class b2, c) is -28 dBm, 42 dB above the desired signal. Assuming a 5 dB NF and a minimum SNR of 12.7 dB, the minimum IIP2 is 26.8 dBm. The most stringent IIP3 requirement is set by L2, L4 test patterns: the maximum interferer level is -35dBm, 47dB above the desired channel, resulting in a minimum IIP3 of -4.4dBm.
