AD9625 Front-End Balun Support

I would need some help with the design of the front-end of the AD9625. In particular with the selection of a correct balun and a the network resistor selection.

My application pretends to use 3GHz bandwidth with 3 NZ and a clock input signal of 2112 MHz.

The signal shoud remain as undistortioned as possible in this 3 GHz range.

I've seen the balun recommended in the evaluation board, but it has the problem of the price. I don't know if I would need to use it to get good features or if I could use some other from Minicircuits or Anaren (in example).


Could anyone help me in the front-end design?


Thanks in advance
