Galaxy Tab powered by ANADIGICS’s Power Amplifiers

ANADIGICS’ AWC6323 power amplifier (PA) can be found in the Samsung Galaxy Tab delivered by Sprint and Verizon Wireless in the US, and ANADIGICS’ AWU6601 PA powers the tablet in the Korean market. Both PAs are part of the ANADIGICS High-Efficiency-at-Low-Power (HELP(TM)) portfolio of products that enhance the performance and efficiency of 3G devices. ANADIGICS’s high efficiency PAs are going to help extending the Tab’s battery life and the user’s mobile broadband experience.

Key features of the ANADIGICS PAs utilized by the Samsung GALAXY Tab:

  • the first ANADIGICS HELP3E(TM) dual-band CDMA PA in a 3 x 5 x 1 mm footprint supporting the Cell (824MHz – 849MHz) and PCS (1850MHz – 1910MHz) bands
  • features the industry’s lowest quiescent current for a CDMA power amplifier, playing an integral role in extending battery life and improving the overall performance of today’s leading mobile devices
  • manufactured on an advanced InGaP HBT MMIC technology, offering state-of-the-art reliability, temperature stability and ruggedness
  • offers three mode states to achieve high-power added efficiencies at several power levels during the phone operation
  • features built-in directional couplers for each band with a common coupler port; this helps eliminate the surface mount couplers placed on the tablet board
  • 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

AWU6601 incorporates ANADIGICS’ HELP3(TM) technology to provide low power consumption without the need for an external voltage regulator
a “daisy-chainable” directional coupler is integrated in the module, eliminating the need for external couplers thus simplifying the device   board layouts
* manufactured on InGaP HBT technology and the self-contained 3 x 3 x 1 mm surface mount package incorporates matching networks optimized for output power, efficiency and linearity
* is HSPA compliant and features simple calibration with only two bias modes
* low quiescent current of 8 mA, low leakage current in shutdown mode at less than 1 uA
* optimised for a 50 O system
* features a RoHS compliant package, 260 degrees C MSL-3
