Citing less demand for high-margin wireless products, RF Micro (Nasdaq: RFMD) said Monday that it will post a loss of 5 cents to 7 cents a share for the fourth quarter.

Even though revenues will be higher than expected – $138.3 million rather than $135 million — the company said it would not break even as had been expected. RF Micro said revenue and demand surged for lower-margin power amplifiers.

Its stock fell some 5 percent, to $5.72, in after hours trading.
