Since the two-frequency switching filter 2 is inserted in the input stage of the two-way divider 3, by switching the two-frequency switching filter 2 to either frequency 1 or 2 , you can receive signals that can switch between 1 and 2 frequencies. Aircraft 4 and 5 had no choice but to switch their reception frequencies to 1 or 2 in conjunction with this.
As a result, the output terminals 6 and 7 could only output one of the transmission signals of reception frequency 1 or 2 .

信機である。 FIG. 2 is a block diagram of one embodiment of the present invention. Input terminal 1 that receives the received signal from the receiving antenna
and a two-way divider 3 connected to this input terminal 1,
Dual frequency switching filters 21 and 22 are connected to the two outputs, respectively, and a dual frequency switching receiver (dual frequency switching receiver) 4 is connected to the two dual frequency switching filters 21 and 22, respectively. 5 and receiver output terminals 6 and 7. The distributor 3 divides the received signal 101 into two parts. Dual frequency switching filters 21 and 22
It consists of two bandpass wavers for frequency 1 and frequency 2 , and a switch that can be used to switch between them. The dual frequency switching receivers 4 and 5 are receivers in which the receiving frequency can be switched to frequency 1 or frequency 2 .
