Berkana Wireless Announces Industry's First True Single-Chip Quad-Band GSM/GPRS Transceiver.Business Editors/High-Tech Writers CAMPBELL, Calif.--(BUSINESS WIRE)--Jan. 13, 2004 BKW9044 Delivers Highest Level of Integration and Enables Significant Cost and Space Reduction in Quad-Band Smartphones and PDAs for World-Wide GSM Roaming Berkana Wireless Inc., a provider of highly integrated CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. RF solutions for wireless connectivity, today announced the world's first true single-chip quad-band GSM/GPRS RF transceiver. Samples of the BKW9044 have already been delivered to lead customers and partners. The BKW9044 is the first single-chip GSM/GPRS RF transceiver to have four complete integrated Low Noise Amplifiers (LNAs) supporting all four worldwide GSM bands: 850 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. , 900 MHz, 1.8 GHz and 1.9 GHz. As a result, both the bill of materials The list of components that make up a system.

The BKW9044 is fabricated in a mature, cost-effective CMOS process and utilizes Berkana's proprietary RF CMOS technology. "The combination of the level of integration along with the RF performance of the BKW9044 true single-chip quad-band transceiver is a compelling value proposition for our customers," said Sam Nakib, VP of Worldwide Sales and Business Development at Berkana. "Digital CMOS is the most cost effective semiconductor technology and our customers recognize that," he added. The BKW9044 is a highly integrated device implementing a complete RF-to-baseband transceiver for quad-band GSM/GPRS cellular handset and wireless data modem A modem used for sending data and not faxes. See modem and fax/modem. applications. The transceiver is fully compatible with all major baseband platforms. It incorporates the complete transmitter, receiver, synthesizer synthesizer Machine that electronically generates and modifies sounds, frequently with the use of a digital computer, for use in the composition of electronic music and in live performance. and baseband interface functionality on a single monolithic IC. All but the power amplifier Power amplifier The final stage in multistage amplifiers, such as audio amplifiers and radio transmitters, designed to deliver appreciable power to the load. and standard receive bandpass SAW filters are integrated on-chip. The device requires only standard decoupling capacitors to implement a complete GSM/GPRS Class 12 transceiver. No external LC filters, transmit filters, transmit baluns, IF SAW filters, or VCO (1) (Voltage Controlled Oscillator) An oscillator that can be tuned over a wide range of frequencies by applying a voltage (tuning voltage) to it. Used in many applications such as radio tuners, VCOs are less costly than crystal oscillators, but not as stable. modules are required. The fully standard compliant receive section consists of differential input LNAs, mixers, and programmable-gain IF filter stages. Very low noise figures are achieved over the four bands for exceptional receive sensitivity. The transmit section provides superior performance, while maintaining low out-of-band spurs and out-of-band phase noise. The high-performance integrated RF synthesizer, which uses Berkana's patented ultra-low-phase noise, fully-on-chip CMOS VCO technology, reduces system cost and improves system reliability substantially. About Berkana Wireless Berkana Wireless Inc. is a Silicon Valley-based fabless semiconductor company A fabless semiconductor company specializes in the design and sale of hardware devices implemented on semiconductor chips. It achieves an advantage by outsourcing the fabrication of the devices to a specialized semiconductor manufacturer called a semiconductor foundry or "fab. that develops highly integrated mixed-signal RF integrated circuits for cellular and other wireless applications using proprietary digital CMOS techniques. Berkana's vision is to deliver dramatic cost, power, and space savings to the cellular phone radio function, and to enable next-generation multi-mode handsets and wireless terminals.
