After 13 obtain signal, the second frequency divider 15 is connected by four throw switch 14 of the second hilted broadsword, B3, B7 RX signal are then passed through three
Receiving filter 17 is sent to the second integrated RF transceiver 18 after filtering and is demodulated.
As shown in Figure 7, Figure 8, for the 4CC network of B1+B3+B7+B20, B7 is PCC main carrier, B1/B3/B20 SCC
Secondary carrier, signal flow refer to the arrow trend in shown in Fig. 9, Figure 10.Since the band signal range of B1 is 1920-
1980MHzTX and 2110-2170MHzRX, corresponding antenna are the second antenna 12, and the band signal range of B3 is 1710-
1785MHzTX and 1805-1880MHzRX, corresponding antenna are the second antenna 12, and the band signal range of B7 is 2500-
2570MHzTX and 2620-2690MHzRX, corresponding antenna are first antenna 11, and the band signal range of B20 is 832-
862MHzTX and 791-821MHzRX, corresponding antenna are the second antenna 12.When uplink emits, B7 is as main carrier, and first
Integrated RF transceiver 1 will up-convert to high-frequency signal from Baseband Receiver to low frequency signal, carry out by linear power amplifier 2
After amplification, five throw switch 8 of the first hilted broadsword is then sent to by tetra- work device 5 of B7, five throw switch 8 of the first hilted broadsword is opened corresponding logical
Road is transferred out by first antenna 11.When reception, to the RX signal of B7, first antenna 11 is used as receiving antenna, by first
Hilted broadsword four-throw 8 is connected to Band7 duplexer 5, directly sends a signal to the first integrated RF transceiver 1 and is modulated；For
The RX signal of B1 and B3, the second antenna 12 are used as receiving antenna, and after carrying out signal frequency split by the first frequency divider 7, signal is sent out
Give the first hilted broadsword five throw switches 9, after five throw switch 9 of the first hilted broadsword gets to that gear switch closure being connected to four work devices 4, directly
It connects and sends a signal to the first integrated RF transceiver 1 and be modulated.For B20 RX signal, first antenna 12 is as reception day
Line after carrying out signal frequency split by the first frequency divider 7, will throw 10 by the second hilted broadsword five and be connected to B20 duplexer 3, directly will
Signal is sent to the first integrated RF transceiver 1 and is modulated.The working principle of its diversity antenna units 20 is third day simultaneously
Line 13 is as just received effect, when work, after third antenna 13 obtains signal, passes through four throw switch 14 of the second hilted broadsword and connects
Then second frequency divider 15 is filtered B1, B3, B7, B20 RX signal by three receiving filters 17 and B20 receiving filter 16
After be sent to the second integrated RF transceiver 18 and demodulated.
As shown in Figure 9, Figure 10, the invention also discloses a kind of separate type adaptive carriers to polymerize implementation method, specific
