Jam rejection of large signal Reception functions are normal in these conditions | When a large signal of 0dBm is added to a frequency 100MHz away from the center, the change of the antenna's in-band gain is less than 2dB. When a large signal of -10dBm is added to a frequency 60MHz away from the center, the change of the antenna's in-band gain is less than 2dB. When a large signal of -20dBm is added to a frequency 50MHz away from the center, the change of the antenna's in-band gain is less than 2dB. |
