NOTES:
3. A = Production Tested, B = Based on Characterization, C = By Design
4. Data is characterized by DC levels applied to MOD TXI and Q pins for 4 quadrants with LO output as reference or indirectly by the SSB
characteristics.
5. Analog mode with an input frequency of 1MHz and an input amplitude of 400mVP-P and a 2.2MHz lowpass filter cutoff with VAGC = 1.25V.
6. Data is characterized with VAGC = 1V with an input of 400mVP-P at LPF_TXI_IN and LPF_TXQ_IN.
