00:00Now it's the coupler's turn. The coupler is a kind of divider.

00:04input two outputs but with the difference that one output loses more

00:08than the other according to the value of the coupler in this case this is a

00:11coupler that we are seeing on the screen of 12 db then already taking and here it is

00:16It tells us the frequency that works from 5 to 1000 MHz taking into account

00:21We notice that here it says i in a centered line that is here here it has

00:26another exit that says tap and this one that says well both are exits but how do you

00:31I say one loses more than the other because this one says out and loses.

00:35maybe a db organization but this one that says tap is going to lose value

00:41the coupler 12 minus 12

00:45Ok, what can we use this passive equipment for and what would its configuration be?

00:50Let's suppose that we have a branch where we only have one or two

00:56tabs so to speak one or two tabs and from there we will extend it further back

01:01our network and if we remove the tab and connect this amplifier there in

01:06your tab place an amplifier and the signal will be very strong it may be that

01:10For example, on carrier number 3 we would be staying and we would arrive by

01:18For example, with 36 we will arrive with 36 in the low, in the high we may arrive from 36 to 42

01:26let's suppose that would be the slope of the 36 42 entry then if that we enter

01:32with that to an amplifier because it is somewhat high we need this one to fall to be able to

01:39connect to the amplifier and it does not cause malfunctions and how we can do it for

01:44knock down the signal by putting a coupler like that, it would be the 12 or the value of 8, let's go

01:49use this one here that says it is valued at 12, it indicates it here so if they are 36 41

01:55we are going to remove 12 then 36 we are going to get to where it says tab which is the one that has the loss we are going to

02:00arrive here 24 and well this little line 41 we subtract what is 12 then it would be 29

02:1029 24 29 already arriving 24 29 this we would already have the option to be able to work the best with this

02:22with an input attenuator where the first hybrid is in the amplifier so that it reaches us

02:28to the first hybrid a good slope if we enter with 24 we are going to put this one, this one, an attenuator for

02:39to be able to lower it at least between 14 and 15 and more or less well here we can put a

02:43a 10 attenuator then we subtract 24 minus 10 and we get 14

02:5129 minus 10 14 19 and with this we can now balance our team
