Analog Devices (News - Alert) has expanded its family of Othello direct conversion radios and its broad TD-SCDMA product portfolio with the Othello-3T AD6552.

The Othello-3T AD6552 expands the company’s legacy as a major provider of solutions for TD-SCDMA wireless handsets. The product is ADI’s second-generation radio and ideal for the 3G TD-SCDMA standard. The new release complements all of the company’s TD-SCDMA baseband chipsets, including SoftFone-LCR and SoftFone-LCR+.

The AD6552 is based on the proven Othello direct-conversion architecture and a novel low-noise transmitter. The product simplifies the development of the radio section of 3G wireless handsets by eliminating the SAW (surface acoustic wave) filters that are usually needed in the transmit path. This results in the reduction of cost and board space.

The receiver section provides EVM performance that supports the requirements for HSDPA and boasts a fully-automatic dc offset control. Analog Devices’ AD6552 integrates virtually all of the necessary components for a handset radio design on a single chip. The company points out that component count for a dual-band radio is reduced by almost 40% in contrast to the previous two-chip Othello-W single-band radio for TD-SCDMA.

“Analog Devices is the only company to offer a complete solution for TD-SCDMA and has built a broad portfolio of solutions for the standard over the past few years,” said Christian Kermarrec, vice president, RF and wireless systems, Analog Devices Inc. in a statement to the press.

According to Kermarrec TD-SCDMA interest is at an all-time high today, with networks being built that can reach 60 million potential subscribers. He believes the latest addition to their TD-SCDMA product family, Othello-3T AD6552, represents a complete and highly-integrated radio for TD-SCDMA handsets, and will enable both domestic Chinese and global handset OEMs to speed time to market and gain a position in China’s emerging 3G market.

Analog Devices is a global manufacturer of high-performance integrated circuits used in analog and digital signal processing applications. Analog Devices is headquartered in Norwood, Massachusetts, with design and manufacturing facilities throughout the world.
