LT5572
TYPICAL PERFOR A CE CHARACTERISTICS VCC = 5V, EN = High, TA = 25°C, fLO = 2.14GHz,
PLO = 0dBm. BBPI, BBMI, BBPQ, BBMQ inputs 0.5VDC, baseband input frequency fBB = 2MHz, I and 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)
