Samsung's Galaxy Tab tablet, billed as a rival of Apple's popular iPad, is utilizing Anadigics Inc.'s power amplifiers (PA).

Anadigics said Samsung selected its AWC6323 PA for the Galaxy Tab, which is offered by Sprint and Verizon Wireless in the United States. It is a HELP3E dual-band CDMA (824MHz-849MHz and 1850MHz-1910MHz) PA measuring just 3x 5x1mm with what the company claims is the industry's lowest quiescent current for a CDMA power amplifier.

The AWU6601 PA, which powers the Galaxy Tab sold in South Korea, offers low-power consumption even without an external voltage regulator. The module integrates a "daisy-chainable" directional coupler, saving space in device board layouts.

The two PAs, manufactured using InGaP HBT MMIC technology, are part of Anadigics' High-Efficiency-at-Low-Power (HELP) portfolio of products designed for 3G devices. The Galaxy Tab is a 7in touchscreen device with a TFT-LCD display and two cameras that uses Android as its OS.
