TYPICAL PERFOR A CE CHARACTERISTICS VCC = 5V, EN = High, TA = 25°C, fLO = 2.14GHz,
PLO = 0dBm. BBPI, BBMI, BBPQ, BBMQ inputs 2.06VDC, 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)
