RF Micro Devices, Inc. (NASDAQ: RFMD), a leading provider of proprietary radio frequency integrated circuits (RFICs) for wireless communications applications, today announced that it has entered the market for DC-DC converter power management components. Concurrently, the Company announced that it has commenced shipments to a tier-one handset manufacturer for use in CDMA handsets.
RFMD's DC-DC converters work with the Company's industry-leading power amplifiers (PAs) and reduce PA current consumption by greater than 50 percent in CDMA and WCDMA applications.
Eric Creviston, corporate vice president of cellular products for RF Micro Devices, said, "We are pleased to announce shipments of our DC-DC converters to a tier-one handset manufacturer. Our DC-DC converters facilitate the trend toward feature-rich, multimode 3G handsets by accommodating the higher data rates without the associated increase in current consumption. By reducing PA current consumption by more than 50 percent, our DC-DC converters help extend the battery life in CDMA and WCDMA applications, which is a top priority among handset manufacturers and consumers."
DC-DC converters expand RFMD's addressable market and increase the Company's content in wireless handsets as well as its silicon product portfolio. RFMD is the market leader in cellular PAs and is a leading supplier of cellular transceiver chipsets.
RFMD's DC-DC converters provide approximately 90% efficiency over a wide output voltage range with minimal ripple. The DC-DC converters are designed using a low-cost silicon process and are packaged in a low-cost leadless package, measuring 3x3mm.
