Downconversion Mixer with LO Buffer/Switch

AC ELECTRICAL CHARACTERISTICS (700MHz BAND DOWNCONVERTER OPERATION)

(Typical Application Circuit, optimized for the 700MHz band (see Table 1), C1 = 7pF, C5 = 3.3pF, L1 and C4 are not used, VCC =

4.75V to 5.25V, RF and LO ports driven from 50Ω sources, PLO = -3dBm to +3dBm, PRF = 0dBm, fRF = 650MHz to 850MHz, fLO =

790MHz to 990MHz, fIF = 140MHz, fLO > fRF, TC = +25°C, unless otherwise noted. Typical values are at VCC = 5V, PRF = 0dBm,

PLO = 0dBm, fRF = 750MHz, fLO = 890MHz, fIF = 140MHz, TC = +25°C, unless otherwise noted.) (Notes 8, 10)

Note 6: Operation outside this range is possible, but with degraded performance of some parameters.

Note 7: Not production tested.

Note 8: All limits include external component losses. Output measurements are taken at IF or RF port of the Typical Application Circuit.

Note 9: Compression point characterized. It is advisable not to continuously operate the mixer RF/IF inputs above +12dBm.

Note 10: Guaranteed by design.

Note 11: Measured with external LO source noise filtered, so its noise floor is -174dBm/Hz. This specification reflects the effects of all

SNR degradations in the mixer, including the LO noise as defined in Application Note 2021: Specifications and Measurements

of Local Oscilator Noise in Integrated Circuit Base Station Mixers.
