why is Simulink Linear FM output of size [100 1]?

When building a radar demo - I connect a Linear FM block to a Transmitter and I receive the following error Expected input TR to be of size [1 1] when it is actually size [100 1]. How can I change this value?

I am using 2016B

Could you provide more context? If you cannot share the model, it would be helpful if you can at least share a snapshot of the diagram. You mention Transmitter in the post but TR input is at ReceiverPreamp. I would need a bit more clarification to look into this issue.
