a. Values are measured at the input of the BCM4319. Thus, they include insertion losses from the integrated
baluns, but exclude losses from the external circuits.
b. The blocking levels are valid for channels 1 through 11. (For higher channels, the performance may be lower
due to third harmonic signals (3 × 824 MHz) falling within band.)
c. Derate by 1.5 dB for –30 °C to –10°C and 55°C to 85°C.
d. Sensitivity degradations for alternate settings in MCS modes. MM: 0.5 dB drop, SGI: 2 dB drop, and STBC: 0.75
dB drop.
e. The minimum and maximum values shown have 95% confidence
