ANADIGICS, a provider of semiconductor solutions for broadband wireless and wireline communications markets, announced the latest version of its dual-band code division multiple access, or “CDMA,” power amplifiers designed for today's most advanced CDMA handsets and data cards for the world's leading wireless providers.

The new power amplifiers, or “PA,” feature a new technology. For the first time, high performance directional couplers have been integrated into a dual band CDMA PA in the 3 X 5 X 1 mm footprint, company officials said.

AWC6323 also promises the lowest quiescent current for a CDMA PA in the industry which helps extend the battery life. AWC6323 offers 3 mode states to achieve high power added efficiencies at several power levels during the phone operation.

They also help reduce the idle current of the power amplifier to industry-best 3.5mA for a CDMA power amplifier. This directly helps in increasing the talk time performance of the handset without the need for a DC-DC converter, company officials said.

AWC6323 PA also features a common output port for the directional couplers built inside the package. These couplers offer 20dB directivity and 22dB coupling factor. This feature helps eliminate the surface mount couplers placed on the phone board.

All of these attributes of AWC6323 directly address the needs of today's advanced handsets and data cards and would enable the handsets to provide an improved consumer experience.

Prasanth Perugupalli, director of the Wireless RF Product Line at ANADIGICS, says that AWC6323 attracts customers mainly because of their high levels of integration in a very small package. The innovations inherent to the AWC6323 help simplify design, reduce component count and save on board space, he added. 

The device also meets the stringent linearity requirements of CDMA EV-DO Revisions A and B modulations, to offer very high data rates for smart phones and data cards, the company said.

The AWC6323 is manufactured on advanced indium gallium phosphide or “InGaP” BiFET MMIC technology, offering the highest levels of reliability, temperature stability and ruggedness.

ANADIGICS also offers a front-end reference design kit or “RDK” for AWC6323, utilizing the most commonly used filters and prescribed matching networks to aid in the phone board design and reduce time-to-market.

The AWC6323 is the flagship PA in ANADIGICS' portfolio of High-Efficiency-at-Low-Power or “HELP” family of CDMA PAs. The company will display the power amplifiers at Mobile World Congress (News - Alert), Feb. 15-18 in Barcelona, company officials said. 

ANADIGICS recently launched AWL9555, a new 5 GHz wireless local area network, or “WLAN,” power amplifier designed to increase both range and data throughput for demanding, high data rate applications.
