T-Mobile USA's new chief executive looks set to dash the hopes of Clearwire Corp investors when he meets Wall Street analysts on Thursday as he is unlikely to announce a strategic deal with the smaller wireless operator, sources close to the situation said.

Philipp Humm, CEO of T-Mobile USA, a unit of Deutsche Telekom , is expected to give analysts a strategy overview for the No. 4 U.S. mobile service provider in New York on Thursday.

Clearwire, which is 54 percent owned by Sprint Nextel , has long been in talks with companies such as T-Mobile USA as it needs billions of dollars in new funding to finish a high-speed wireless network it is building.

Clearwire and T-Mobile USA are still in active talks about options including a spectrum sale or a T-Mobile USA equity investment in Clearwire, according to two of the sources who asked not to be named as talks are ongoing.

Some analysts are hoping T-Mobile USA, which will needs access new spectrum in coming years, would be ready to announce a deal with Clearwire at its analyst meeting.

A representative for T-Mobile USA declined to discuss the contents of Humm's planned presentation.
