+3.3V SUPPLY AC ELECTRICAL CHARACTERISTICS

(DOWNCONVERTER OPERATION) (continued)

(Typical Application Circuit with tuning elements outlined in Table 1, RF and LO ports are driven from 50I sources. Typical values

are for TC = +25NC, VCC = +3.3V, PRF = 0dBm, PLO = 0dBm, fRF = 2600MHz, fLO = 2300MHz, fIF = 300MHz, unless otherwise

noted.) (Note 7)
