OPA4354: Wide Bandwidth 90 Degrees Phase Shifter Amplifiers

Part Number: OPA4354

Hi, 

I am trying to design a 90 degree phase shifter circuit like http://www.ti.com/corp/docs/university/pdf/adc2012_politecnico_di_milano.pdf 

need help to decide component value? Is there is any IC available which can perform same task?
