大信号阻塞Jam rejection of Large Signal

在偏离中心频率100MHz 的频率上加10dBm 大信号时，GPS+北斗双模天线带内增益变化小于2dB；在偏离中心频率60MHz 的频率上加0dBm 大信号时，GPS+北斗双模天线带内增益变化小于2dB；在偏离中心频率50MHz 的频率上加－10dBm 大信号时，GPS+北斗双模天线带内增益变化小于2dB。在以上情况下GPS 接收机能正常工作。

The in band gain change of GPS + BD dual-mode antenna is less than 2dB when adding 10dBm large signal to the frequency of 100MHz off center frequency; less than 2dB of in band gain change of GPS + BD dual-mode antenna when adding 0dbm large signal to frequency of 60MHz off center frequency; and less than 2dB of in band gain change of GPS + BD dual-mode antenna when adding - 10dBm large signal at frequency of 50MHz off center frequency. Under the above conditions, the GPS receiver can work normally.
