Sorry to bother you~enashjdobler

In the datasheet, I saw the differential impedance is 400 ohm. And in the following circuit, I wanna change the  differential to the single end. In the evaluation board, I noticed that the impedance ratio of the following RF transformer was 2:1. Considering the match impedance is 50 ohm, the RF transformer can only transform the 400 ohm differential impedance into 200ohm not 50ohm often served as default match impedance . So is there some problems in the design? Thanks.The attachments are as follows
