The second radio frequency path, but the first radio frequency path and the second radio frequency path are different to the rejection ability of intermediate frequency with high frequency respectively.
Specifically, for example, the CA group of intermediate frequency B1 and high frequency B7 is combined into B1+B7 polymerization electromagnetic wave, after multithrow switch pair is opened,
After the first connecting pin and 2 second connection ends are simultaneously turned on, intermediate frequency B1 and high frequency B7 can by the first radio frequency path and
Second radio frequency path.
Assuming that filter X is intermediate frequency B1 filter, filter Y is high frequency B7 filter, and B1+B7 polymerization electromagnetic wave first passes through
Phase shift match circuit on first radio frequency path, then through wave filter X, the decaying of B1 at this time only has 1-2dB, and B7 decaying reaches
To 70-80dB；Similarly, B1+B7 polymerization electromagnetic wave first passes through the phase shift match circuit on the second radio frequency path, then by filtering
Device Y, the decaying of B7 at this time only has 1-2dB, and B1 decaying reaches 70-80dB.In this way, most of energy of B1 can be penetrated from first
Frequency access reaches transceiver, and most of energy of B7 can reach transceiver from the second radio frequency path, realize the effect of shunting.
