Skyworks Unveils Complete Radio Subsystem for EDGE Mobile Handset Platforms
Patent-pending polar modulation technology reduces complexity, size, cost, and power requirements for next-generation platforms
WOBURN, Mass.--July 21, 2003--Skyworks Solutions, Inc. (NASDAQ: SWKS), the industry's leading wireless semiconductor company focused on radio frequency (RF) and complete cellular system solutions for mobile communications applications, introduced a complete RF subsystem for E-GPRS (GSM/GPRS/EDGE) mobile handsets. Skyworks' RF chip-set solution includes the company's leadership single-chip direct-conversion transceiver, power amplifier (PA) module, and a PA controller/modulator.
Skyworks' new subsystem uses a patent-pending Polar Loop transmit-modulation architecture, which eliminates expensive components such as SAW filters to save handset designers significant space, cost, and design-cycle time with improved performance. This approach has the potential for improving PA efficiency in EDGE mode by up to 10 percent when compared to conventional architectures, resulting in improved talk times.
EDGE, or Enhanced Data Rates for GSM Evolution, is a wireless communications technology that allows consumers to use cellular handsets, PC cards, PDAs, and other wireless devices to connect to the Internet at data rates up to four times faster than existing GSM and GPRS wireless devices.
"Skyworks continues to extend its leadership in RF subsystems and PAs, with a three-chip solution that enables customers to quickly enter the rapidly emerging market for EDGE-based wireless data services," said Mohy Abdelgany, vice president of RF Systems for Skyworks. "Our innovative Polar-Loop modulation technique provides significant improvements in BOM reductions and power efficiency, and will give designers a powerful solution for developing next-generation E-GPRS handsets."
Skyworks' complete radio subsystem includes all the necessary RF components for building state-of-the-art quad-band (850/900/1800/1900) handsets. At the heart of the solution is the company's advanced Polar-Loop transmit-modulation architecture. This unique approach enables the radio to transmit both constant and nonconstant envelope signals through the same transmit path to minimize the number of external components required to build a mobile handset. In addition, the architecture significantly reduces the complexity, size, cost, and power requirements of next-generation EDGE platforms.
Skyworks' Polar-Loop technology leverages saturation-mode PA technology, the industry's dominant approach for GSM terminals, to maximize power-added efficiency (PAE) in EDGE modulation (8-phase-shift keying). This is done in an extremely robust closed-loop system. The three-chip solution enables the system to perform well under extreme Voltage Standard Wave Ratio (VSWR) conditions up to a 6:1 ratio, while not requiring the use of an external isolator. This further reduces the cost and size of the system.
The highly integrated subsystem includes:
- SKY74045 Direct-Conversion TransceiverThe SKY74045 is based on Skyworks' full type-approved (FTA) single-chip direct-conversion transceiver technology, which is included in more than 50 mobile platforms. The RF transceiver consists of a direct-conversion receiver, a transmitter with integrated voltage-controller oscillators (VCO) that uses Skyworks' Polar-Loop modulation technology, and a fully integrated Fractional-N synthesizer.
Skyworks' advanced direct-conversion architecture technology eliminates the need for special baseband processing requirements to provide customers with the flexibility to combine the subsystem with virtually any E-GPRS baseband solution currently available on the market.
The quad-band SKY74045 RF transceiver, when combined with the SKY74046 PA controller/modulator, seamlessly forms a closed-loop transmit system around the SKY77316 PA.
The SKY74045 is fabricated using BiCMOS technology, and is available in a 56-pin 8 mm × 8 mm land-grid array (LGA) package.
- SKY74046 PA Controller/ModulatorThe PA controller is a highly integrated device used for power control, and when combined with the SKY74045 transceiver enables the transmit of both constant and nonconstant envelope signals. The device requires a minimal number of external components to complete an automatic output control loop. The SKY74046 is fabricated using BiCMOS technology, and is available in a 24-pin 4 mm × 4 mm land-grid array (LGA) package.
- SKY77316 PA ModulePA functionality is provided by a proven Skyworks module that incorporates a GSM850/900 PA block, a DCS1800/PCS1900 PA block, impedance-matching circuitry for 50 W input and output, and a PA bias control block. The two separate HBT PA blocks are fabricated on a single gallium arsenide (GaAs) die to provide maximum performance in a small footprint. The SKY77316 is available in a 16-pin 8 mm × 10 mm multichip module (MCM).
Pricing and Availability
Skyworks' complete EDGE RF subsystem solution is sampling now, with volume production scheduled to take place in the fourth calendar quarter of 2003. The module is priced at $8.50 in quantities of 10,000.
Skyworks Unveils the Industry's First Fully Integrated 802.11b/g Wireless LAN Front-End Module
Combines PA, switch, and filter functionality in a single integrated package
WOBURN, Mass.--June 9, 2003--Skyworks Solutions, Inc. (NASDAQ: SWKS), the industry's leading wireless semiconductor company focused on radio frequency (RF) and complete cellular system solutions for mobile communications applications, introduced the industry's first fully integrated 802.11b/g wireless LAN front-end module. The new SKY65201 significantly reduces the number of components required for building wireless LAN router, access point, PC card, and PCI adapter access points.
Designed with cost and space savings in mind, the SKY65201 wireless LAN front-end module combines the company's industry-leading power amplifier (PA), switch, and filter functions into a single low-cost, 8 mm × 10 mm package.
According to market-research firm In-Stat/MDR, wireless LAN chip sets more than doubled to over 20 million units in 2002. In-Stat expects that number to grow to over 94 million by 2007. "Skyworks' new wireless LAN front-end module will be extremely attractive to companies without RF experience," said Allen Nogee, principal analyst with In-Stat/MDR. "The ability to drop in the RF front-end will enable quicker time-to-market for wireless LAN developers, and ultimately reduce costs and accelerate 802.11 adoption."
"Skyworks' wide breadth of leadership products and process technologies enabled us to design a fully integrated wireless LAN module that will allow customers to deliver high-performance wireless LAN devices with minimum design time, at a reduced cost," said Gregory Waters, Skyworks' vice president of Cellular Infrastructure and Wireless Data. "Initial samples have already achieved the acclaim of a number of top-tier customers, and we expect to see new wireless LAN devices integrating our new module on shelves by the end of the year."
Key features of the new SKY65201 module include a high-performance PA, transmit/receive switch, band pass (BP) and low pass (LP) filtering, as well as all associated control functions with no external matching components. The module delivers an output power of 21 dBm for 802.11b, or 16 dBm for 802.11g applications, with 29 dB of gain at a bias of 3.3 V.
Skyworks' SKY65201 wireless LAN module is manufactured using Skyworks' proprietary heterojunction bipolar transistor (HBT) power amplifier process, low-loss pseudomorphic high-electron-mobility transistor (PHEMT) switch process, and low-temperature cofired ceramics (LTCC) filter process technologies.
Price and Availability
The SKY65201 module is available now, and is priced at $2.25 in volumes of one million.
