Galaxy Tab uses Anadigics power amplifiers
Keywords:power amplifier? Galaxy Tab? MMIC?
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.
