phase shifter

Hi i want to buy a phase shifter with following specifications (1)Frequency range: 10KHz to 1MHz. (2)Phase shift:+/-90 degree only, (3) Power: 1-10W. for this i search on many website and at the last i found AD8333 EVALZ board which may fullfill my requirement, but i have some question for this board. (1) will it able to provide 90 degree phase shift without applying 4LOP and 4LON connection?? (2) will it able to provide phase shift in broad band as per my application requirement?? (2) Will it take 1-10W power?? please help
