Please help me to find a proper wideband transformer

[Hanqing Xing]

Hi. I need some transformers to do some testing. The specifications are as
follows:

it is a signal coupling transformer (not a power transformer). The turns
ratio is 1:2, or equivalently, the impedence ratio is 1:4; the lowest
frequency is about 100Hz or 1kHz; the highest frequency is about 10MHz; the
inserton loss should be small; the transformer is used to couple a single
ended signal to a differential signal; the input voltage to the transformer
is small, usually less than 5 volt

Does anyone know where I can find this kind of transformers?

Thanks in advance.
