Large signal blocking (the receiver can operate normally under these conditions) Active Gain Operating Voltage Operating Current | When a 0 dBm large signal is applied at a frequency 100 MHz offset from the center frequency, the in?band gain variation of the antenna is less than 2 dB. When a -10 dBm large signal is applied at a frequency 60 MHz offset from the center frequency, the in?band gain variation of the antenna is less than 2 dB. When a -20 dBm large signal is applied at a frequency 50 MHz offset from the center frequency, the in?band gain variation of the antenna is less than 2 dB. 38±2 dB 3 V～8 V ≤ 40 mA | |
