grew its bottom line almost four-fold in the second quarter, as sales of the company's communications chips continued to surge.

In the three months ended June 30, Broadcom raked in sales of $1.2 billion, above the average analyst expectation of $1.1 billion.

At this time last year, Broadcom had sales of $897.9 million.

Broadcom posted net income of $134.8 million, or 25 cents a share, vs. $34.3 million, or 6 cents a share, at this time last year.

The results included $127 million in stock compensation expenses.

It was not immediately clear how the results compared with the average analyst EPS expectation of 36 cents, which do not include stock compensation expenses.

Shares of Broadcom rose 2% to $28.18 in recent after-hours trading.

"Despite the continued economic turmoil, demand for Broadcom's wired and wireless communications products strengthened in the second quarter," CEO Scot McGregor said in a statement.

Broadcom did not provide financial guidance for the current quarter, although the company is slated to hold a conference call discussing its quarterly results later Tuesday.
