LO Leakage Distribution

VCC = 5V, EN = High, TA = 25°C, fLO = 900MHz,

fRF = 902MHz, PLO = 0dBm. BBPI, BBMI, BBPQ, BBMQ CM input voltage = 0.5VDC, Baseband Input Frequency fBB = 2MHz, I & Q 90°

shifted, without image or LO feedthrough nulling. fRF = fBB + fLO (upper sideband selection). PRF(OUT) = –10dBm (–10dBm/tone for 2-

tone measurements), unless otherwise noted. (Note 3)
