Maxim Integrated 

High-Linearity, 650MHz to 1000MHz Upconversion/

Downconversion Mixer with LO Buffer/Switch

AC ELECTRICAL CHARACTERISTICS (800MHz/900MHz CELLULAR BAND DOWNCON-

VERTER OPERATION)

(Typical Application Circuit, optimized for the 800MHz/900MHz cellular band (see Table 1), C1 = 82pF, C5 = 2pF, L1 and C4 not

used, VCC = 4.75V to 5.25V, RF and LO ports driven from 50Ω sources, PLO = -3dBm to +3dBm, PRF = 0dBm, fRF = 815MHz to

1000MHz, fLO = 960MHz to 1180MHz, fIF = 160MHz, fLO > fRF, TC = -40°C to +85°C, unless otherwise noted. Typical values are at

VCC = 5V, PRF = 0dBm, PLO = 0dBm, fRF = 910MHz, fLO = 1070MHz, fIF = 160MHz, TC = +25°C, unless otherwise noted.) (Note 8)
