Jam rejection of large signal
|
When adding a 10dBm large signal at the 100MHz off central frequency, GPS&BDS antenna’s gain will change less than 2dB. When adding a 0dBm large signal at the 60MHz off central frequency, GPS&BDS antenna’s gain will change less than 2dB. When adding a -10dBm large signal at the 50MHz off central frequency, GPS&BDS antenna’s gain will change less than 2Db. Under all the above conditions, the GPS receiver can work normally. |
