The ADMV4540 provides an uncalibrated 35 dBc of image rejection. The image rejection can be further optimized by tuning the phase bits (LO_PHASE_I, Register 0x128, Bits[2:0], and LO_PHASE_Q, Register 0x128, Bits[5:3]), which have up to 6° of phase range and approximately 0.4° resolution, and by tuning the 0.1 dB DSA bits (SEL_BB_ATT_I, Register 0x140, Bits[3:0], and SEL_BB_ATT_Q, Register 0x140, Bits[7:4]) with up to a 1.5 dB range.
