SiGe High-Linearity, 1400MHz to 2200MHz Downconversion Mixer with LO Buffer/Switch

Maxim Integrated 

SiGe High-Linearity, 1400MHz to 2200MHz

Downconversion Mixer with LO Buffer/Switch

AC ELECTRICAL CHARACTERISTICS—fRF = 1700MHz TO 2200MHz, LOW-SIDE LO INJECTION

(Typical Application Circuit, VCC = +4.75V to +5.25V, RF and LO ports are driven from 50Ω sources, PLO = -3dBm to +3dBm,

PRF = -5dBm, fRF = 1700MHz to 2200MHz, fLO = 1400MHz to 2000MHz, fIF = 200MHz, fRF > fLO, TC = -40°C to +85°C, unless other-

wise noted. Typical values are at VCC = +5V, PRF = -5dBm, PLO = 0dBm, fRF = 1900MHz, fLO = 1700MHz, fIF = 200MHz,

TC = +25°C, unless otherwise noted.) (Notes 4, 5)
