ANADIGICS Introduces multi-mode, high- performance power amplifiers
2010-03-16
Industry’s Most Efficient Power Amplifiers for Emerging 4G LTE and 3G HSPA+ Mobile Market
ANADIGICS,
Inc.today introduced a new set of multi-mode, high-performance power amplifiers
(PAs) designed for wireless datacards and handsets for the rapidly emerging 4G Long Term Evolution (LTE) and advanced HSPA+ technologies.
These new single-band PAs are built using the fourth generation of ANADIGICS’ patented HELP (High-Efficiency-at-Low-Power) technology to deliver exceptional performance to customers making USB modules and new generation handsets based on the LTE standard.
Analyst firm Gartner states that LTE is on track to become one of the dominant 4G technologies for mobile broadband within this decade. By 2015, LTE coverage is expected to reach at least 50 percent of all mobile subscribers in the United States and Western Europe. The ANADIGICS HELP4 LTE family of PAs has been designed to meet the stringent linearity needs of LTE modulation and offer the highest power and efficiency in the industry.
“We are proud to continue driving innovation in power amplifier technology for mobile applications as the industry expands beyond WCDMA toward LTE for 4G applications,” stated Prasanth Perugupalli, Director of Wireless RF Products Line at ANADIGICS. “With the HELP4™ family, we have reduced the average current consumption by an impressive 30% over previous generation PAs. We also continue to lead the industry in terms of performance in current savings at the frequently used low power levels in handsets.”

family includes the ALT6701, ALT6702, ALT6704, ALT6712 and ALT6713 products, which are tailored to cover UMTS and LTE bands 1, 2, 4, 12 and 13 that are available across various geographic locations including the USA, Japan, Western Europe and China.
Each of these devices is now available for customer sampling; evaluation kits are also available upon request. Volume ramp into production is aligned with market needs to meet customer design cycles for introduction of the industry’s earliest datacard modules for LTE networks.
Key Product Facts and Highlights:
• ALT6701, ALT6702, ALT6704, ALT6712 and ALT6713 are packaged in a 10-pin 3x3x1 (mm). • This family of PAs features the lowest Quiescent current in the industry (3mA). • Each device has been thoroughly characterized under 16-QPSK, 64-QAM and HSPA+ modulations to ensure compatibility with high bandwidth applications. • An integrated “daisy chainable” directional coupler with 20dB directivity is included inside the package. • This family offers three mode states to maximize power-added efficiency at several power levels during the operation of an LTE handset.
Specific Applications:
• ALT6701: Band 1 LTE wireless devices; Band 1 (IMT) WCDMA/HSPA
wireless devices; and Band Class 6 CDMA/ EVDO wireless devices • ALT6702: Band 2 LTE wireless devices; Band 2 (PCS) WCDMA/HSPA
wireless devices; and Band Class 1 CDMA/ EVDO wireless devices • ALT6704: Band 4 LTE wireless devices; Band 4 (IMT) WCDMA/HSPA
wireless devices; and AWS/KPCS CDMA/ EVDO wireless devices • ALT6712: Band 12 and 17 LTE wireless devices • ALT6713: Band
