Downconversion Mixer with LO Buffer

+3.3V SUPPLY DC ELECTRICAL CHARACTERISTICS

(Typical Application Circuit optimized for the standard RF band (see Table 1), no input RF or LO signals applied, VCC = 3.0V to 3.6V,

TC = -40°C to +85°C. Typical values are at VCC = 3.3V, TC = +25°C, unless otherwise noted. R1, R4 = 1.1kΩ, R2, R5 = 845Ω.)
