Anadigics introduces new family of WCDMA/HSPA PAs

Anadigics Inc of Warren, NJ, USA has launched a new family of WCDMA/HSPA power amplifiers (PAs) that incorporate daisy-chainable RF power couplers which enable simplified design of 3G handsets, data cards, modems and other types of UMTS subscriber devices.

Based on the firm’s HELP3 technology, the new Anadigics 3x3mm integrated PAs are designed for 3G WCDMA/HSPA and HSPA+ mobile devices, and deliver both the high output power, low battery current consumption and linearity required by advanced 3G networks, says the firm.

The RF coupler in each PA has typical 20dB directivity and 20dB coupling factor. Coupler input and coupler output ports enable ‘daisy-chain’ RF designs, which greatly simplify multiband 3G device board layouts. Each power amplifier in this family is designed for optimized performance in a specific UMTS band:

• AWU6601 for UMTS2100 (Band 1)
• AWU6602 for UMTS1900 (Band 2)
• AWU6604 for UMTS1700 (Bands 3, 4 & 9)
• AWU6605 for UMTS850 (Bands 5 & 6)
• AWU6608 for UMTS900 (Band 8)

“These new WCDMA power amplifiers are the ideal choice for 3G phones designed for single, dual, or multiple UMTS bands,” says Prasanth Perugupalli, WCDMA/CDMA Product Line director at Anadigics. “Their common footprint and built-in RF couplers give phone designers wider latitude in component placement and routing. In addition, the 2-state logic simplifies phone calibration and shortens calibration time. Each device’s performance is fully compliant with UMTS mobile device requirements through Release 7 to assure spec-compliant performance in platforms based on all leading WCDMA (UMTS) chipsets.”

Anadigics’ WCDMA products are manufactured using the firm’s proprietary InGaP-Plus technology, and a material set consistent with the European Union's Restriction of Hazardous Substances (RoHS).

The new products are sampling to selected customers, with volume production starting in Q3/2009.
