I , Q = 1 Vp-p implies that the magnitude of the signal at each input pin IVIN, IREF, QVIN, QREF is equal to 500 mVp-p.
USB = upper sideband. LSB = lower sideband.
Maximum noise values are assured by statistical characterization only, not production testing. The values specified are over the entire
temperature range, T A = –40 ° C to 85 ° C.
For a listing of impedances at various frequencies, see Table 1 .
After optimization at room temperature. See the Definitions of Selected Specifications section.
