Dual-band CDMA power amplifier from Anadigics for mobile handsets

Anadigics has introduced the AWC6323, a new dual-band CDMA power amplifier (PA) that contains independent RF PA paths to ensure optimal performance in both frequency bands, while achieving a 25% PCB space savings compared with solutions requiring two single-band PAs. The AWC6323 is suitable for CDMA mobile handsets and data cards.

The key features of the AWC6323 PA are,

InGaP HBT technology
High efficiency of 38 % at +27.6 dBm, 22 % at +16 dBm, and 11 % at +10 dBm
<4 mA of low quiescent current
Internal voltage regulation
Built-in directional coupler
Common VMODE control line
Simplified VCC bus PCB routing
Reduced external component count
RoHS compliant package, 260 ºC MSL-3

Anadigics says, the AWC6323 offers 3 mode states to achieve high power added efficiencies at several power levels during the phone operation. It also helps reduce the idle current of the power amplifier to 3.5mA for a CDMA power amplifier. This helps in increasing the talk time performance of the handset without the need for a DC-DC converter.

"The AWC6323 has received tremendous response from our customers. Customers are particularly enthusiastic about the high levels of integration in a very small package. The innovations inherent to the AWC6323 help simplify design, reduce component count and save on board space. These attributes directly address the needs of today's advanced handsets and data cards," said Prasanth Perugupalli, Director of the Wireless RF Product Line at ANADIGICS. "ANADIGICS is also offering extensive support for our customers through a front-end reference design kit, utilizing the most commonly used filters and prescribed matching networks to aid in the phone broad design and reduce time-to-market."
