OBS_O_3 < -60 -47 dBm 1.8 GHz ~ 1.9 GHz OBS_O_4 < -65 -47 dBm 5.15 GHz ~ 5.3 GHz Note: 1. The test is run at one midband frequency, typically 2460 MHz. With blocking frequency swept in 1 MHz steps, up to 24 exception frequencies are allowed. Of these, no more than 5 shall persist with blocking signal reduced to -50dBm. For blocking frequencies below desired receive frequency, in-band harmonics of the out-of-band blocking signal are the most frequent cause of failure, so be |
