design and characterization.

Note 3: Input gain range specifications met over this band.

Note 4: In-band IIP3 test conditions: GC1 set to provide the nominal baseband output drive when mixing down a -23dBm tone at

-26dBm each are applied at 1919MHz and 1663MHz. The IM3 tone at 3MHz is measured at baseband, but is referred to the

RF input.

Note 5: Out-of-band IIP3 test conditions: GC1 set to provide nominal baseband output drive when mixing down a -23dBm tone at

-20dBm each are applied at 1919MHz and 1663MHz. The IM3 tone at 5MHz is measured at baseband, but is referred to the

RF input.

Note 6: Input IP2 test conditions: GC1 set to provide nominal baseband output drive when mixing down a -23dBm tone at 2175MHz

each are applied at 925MHz and 1250MHz. The IM2 tone at 5MHz is measured at baseband, but is referred to the RF input.

Note 7: See Table 16 for crystal ESR requirements.
