Broadcom (UNKNOWN:BRCM.DL) is broadcasting some encouraging news to its investors. The company this week updated the guidance for its current Q4 2013, saying it now expects $2.00 billion to $2.05 billion in revenue. This is a higher range than the firm's previous projection of $1.92 billion to $2.03 billion. 

The upper end of the range, however, is below the $2.15 billion top line Broadcom posted in its Q3. 

Meanwhile, the company anticipates lower costs for the current quarter when compared to prior estimates. On a GAAP basis, research and development spending, combined with selling, general, and administrative expenses, should amount to $820 million to $840 million; the previous range was $830 million to $850 million.

Broadcom said the new net revenue figures were due to "better-than-expected revenue in each reportable segment, particularly in Infrastructure & Networking." It also cited "tighter expense management."
