Return loss
a. Derate by 1.5 dB for –30 °C to –10°C and 55°C to 85°C.
b. Sensitivity degradations for alternate settings in MCS modes. MM: 0.5 dB drop, SGI: 2 dB drop, and STBC: 0.75
dB drop.
c. The cellular standard listed for each band indicates the type of modulation used to generate the interfering
signal in that band for the purpose of this test. It is not intended to indicate any specific usage of each band
in any specific country.
d. The blocking levels are valid for channels 1 to 11. (For higher channels, the performance may be lower due to
third harmonic signals (3 × 824 MHz) falling within band.)
e. The minimum and maximum values shown have a 95% confidence level.
