AD9361 RX port Impedance

I would like to improve my current design with better matching circuit on the Rx Differential ports.

How should I consider RX1A, RX1B and RX2A differential port impedance: 100 or 200 Ohm?

I'm targeting those ports to be used with the following 2 options:


1. Wideband ports (RX1A, 1B and 2A) 700-2600MHz Or-

2. Ports shell be divided to several ranges:
     700-1000MHz (RX1A)

     1800-2200MHz (RX1B)

     2500-2600 (RX2A)


I'm going to use a balanced to unbalanced transformer (as an example Aneren Xinger models)

Appreciate your reply,
