(Telecompaper) Broadcom has raised its guidance for fourth-quarter results, citing better sales in particularly the networking market. The semiconductor maker now expects revenues of USD 2.00-2.05 billion, versus around USD 1.975 billion previously, saying sales were better than expected in all product segments and especially Infrastructure & Networking. This means the gross margin will fall less than expected, down around 50-75 basis points rather than 50-100 points. Tighter cost control also means R&D and SG&A expenses will increase less than forecast previously, by around USD 30-50 million rather than USD 40-60 million.
