BASEBAND QUADRATURE DEMODULATION TO
VERY LOW FREQUENCIES
Figure 107 to Figure 111 show the I/Q mode performance at
low baseband frequencies. The measurements were performed
at 28 GHz, −25 dBm input power, VCM = 1.15 V, Register 0x03,
Bit 11 = 1, Register 0x03, Bit 8 = 0, 6 dBm LO input power, and
TA = 25°C.

PERFORMANCE AT DIFFERENT QUAD FILTER
SETTINGS
Figure 112 shows the conversion gain vs. RF frequency in IF
mode at 25°C and LO input power = 6 dBm, for different
QUAD_FILTERS settings. Figure 113 shows the LO to IF_I and
LO to IF_Q leakage vs. LO frequency at different quad filter
settings.
