GREENSBORO, N.C., April 7, 2009 (GLOBE NEWSWIRE) -- RF Micro Devices, Inc. (Nasdaq:RFMD), a global leader in the design and manufacture of high-performance semiconductor components, today announced it has extended its portfolio of integrated configurable components to include products for the cellular repeater and Wireless Local Area Network (WLAN) markets. The new integrated configurable components include the RF2057 RF synthesizer with integrated mixers and the RF2059 RF transverter.
RFMD's integrated configurable components deliver unmatched levels of flexibility and functional integration to designers of radio systems. By integrating multiple common radio frequency (RF) functions into highly integrated, size-reduced packages, the integrated configurable components enable designers to develop radio systems that operate over a wide dynamic range and across a broad range of frequencies and channel bandwidths. The RF2057 and RF2059 join the RF2051, RF2052 and RF2053, which were introduced in April 2008 and have been adopted in markets as diverse as cellular, defense and broadband cable systems.
Alastair Upton, general manager of RFMD's Broadband Products business unit, said, "The RF2057 and RF2059 demonstrate RFMD's commitment to delivering valuable innovations that support our customers' success. The unique system partitioning and functional integration of RFMD's integrated configurable components help radio designers shrink circuit board area, reduce risk, simplify implementation and shorten product development time, thereby lowering the cost of implementation."
Highlights of the new integrated configurable components include:
RF2057 RF Synthesizer
The RF2057 RF synthesizer provides designers of cellular repeaters an improved level of integration within the performance parameters required to meet the W-CDMA/PCS specifications for pico and mini repeaters. Repeaters are used to extend the range of cellular networks and to provide coverage in cellular "dead" spots.
The RF2057 includes all functions required for frequency downconversion and upconversion, a fractional-N phase locked loop (PLL) synthesizer capable of tuning accuracy of approximately 1Hz, a wideband monolithic voltage controlled oscillator (VCO) with a tuning range of 1900MHz to 2400MHz, local oscillator (LO) drivers and two double-balanced wideband mixers with a minimum IIP3 of +18dBm.
By integrating the interface between the VCOs and mixers, the RF2057 can deliver highly reliable operation at published specifications, significantly reducing design time and risk in radio implementation. Additionally, by combining the PLL, VCO, LO path and mixers into a single 5x5mm package, the RF2057 delivers a size-reduced solution for low- to mid-power cellular repeaters that provides superior flexibility in implementation.
RF2059 RF Transverter
The RF2059 RF transverter provides designers of WLAN systems a size-reduced and simplified solution for converting RF signals between the 2.4GHz and 900MHz ISM bands. The RF2059 is placed between the WLAN chipset and the RF front end, and all functionality necessary for frequency conversion is integrated on-chip.
The RF2059 contains a PLL synthesizer, a VCO capable of meeting WLAN linearity and accuracy requirements and two double-balanced mixers for receive and transmit paths. By integrating the synthesizer, VCOs and mixers on-chip, combined with the buffer circuits usually required to implement the functions discretely, the RF2059 delivers significant circuit board space savings and simplicity of implementation, versus typical discrete implementations, with negligible signal degradation (typically less than 0.8% RMS). The RF2059 is programmed and controlled through a simple 3-wire interface and housed in a compact 5x5mm package. The RF2059 transverter can also be used in certain cellular repeater systems.
The RF2057 and RF2059 are priced at $5.60 in quantities of 1,000. Samples and high volume production quantities are available immediately. For more information please see www.rfmd.com/RF205x.
