Embodiment 1
[0021] In this embodiment, a multifunctional combiner, such as figure 1 As shown, it includes four signal input terminals 5, four signal buffer areas 3, four signal optimization units 4, three switches 6, two signal control units 2 and two signal output terminals 1, and the signal input terminals and signal optimization The units are connected, the signal optimization unit is connected to the signal buffer area, a switch is provided between two adjacent signal buffer areas, the signal buffer areas on both sides are respectively connected to the signal control module, and the signal control module is connected to the signal output terminal.
[0022] The combiner controls a variety of signal combinations through the switches arranged between the signal buffer areas. The three switches are set as the first switch, the second switch, and the third switch from left to right. When the three switches are all closed, the two The two signal output terminals output the same combination ...
Embodiment 2
[0027] This embodiment is a multifunctional combiner. Compared with Embodiment 1, the signal optimization unit is a signal amplification unit, and the signal amplification unit is such as image 3 As shown, the signal amplifying unit includes a signal amplifying module 10 , a filtering module 11 and an isolation module 12 connected in sequence. The signal amplification module adopts the INA118 chip of BB Company.
Embodiment 3
[0029] This embodiment is a multifunctional combiner. Compared with Embodiments 1 and 2, the signal optimization unit is a combined unit composed of a signal denoising unit and a signal amplifying unit, and the signal amplifying unit is connected behind the signal denoising unit.
