It is applied in TV technique for joint operation of two transmitters with different frequencies (video and sound signal support), loaded on one general (common) antenna.
Prevents mutual influence of transmitters and their cross modulation.
The device is made as double, 3-dB stubbed bridge with two band rejection filters.
|Range frequencies||470…780 MHz|
|Operating frequency band||10 MHz|
|Losses of a path:|
|-sound support||1,5 dB|
|– of the video-signal||0,6 dB|
|Power suppression of one transmitter to the input of other||30 dB|
