Warren, N.J. — Anadigics, Inc. has launched a new set of multi-mode, high-performance power amplifiers (PAs) designed for wireless datacards and handsets for the emerging 4G long term evolution (LTE) and advanced HSPA+ technologies. These single-band PAs are built using the fourth generation of Anadigics’ patented High-Efficiency-at-Low-Power (HELP) technology for customers manufacturing USB modules and new generation handsets based on the LTE standard.
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, said the company. The devices claim the lowest quiescent current in the industry (3 mA). The latest devices also offer a reduced average current consumption of 30 percent over the previous generation PAs.
The HELP4 LTE power amplifier 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 U.S., Japan, Western Europe and China. Each device has been characterized under 16-QPSK, 64-QAM and HSPA+ modulations to ensure compatibility with high bandwidth applications.
The ALT6701, ALT6702, ALT6704, ALT6712 and ALT6713 devices are housed in a 10-pin 3 x 3 x 1-mm package. An integrated “daisy chainable” directional coupler with 20-dB directivity is included inside the package.
This family offers three mode states to maximize power-added efficiency at several power levels during operation of a LTE handset.
Here’s the product line-up by 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 13 and 14 LTE wireless devices
Availability: All devices are now available for customer sampling. Evaluation kits are also available on request.
