AWC6323

Description: 
3.4 V Dual-band Cellular & PCS CDMA Linear PAM

AWC6323 addresses the demand for increased integration in dual-band handsets for CDMA networks. The small footprint 3 mm x 5 mm x 1 mm surface mount RoHS compliant package 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 package pinout was chosen to enable handset manufacturers to easily route bias to both power amplifiers and simplify control with common mode pins. The device is manufactured on an advanced InGaP HBT MMIC technology offering state-of-the-art reliability, temperature stability, and ruggedness. The AWC6323 is part of ANADIGICS’ High-Efficiency-at-Low-Power (HELP™) family of CDMA power amplifiers, which deliver low quiescent currents and significantly greater efficiency without the need of an external DC-DC converter. Through selectable bias modes, the AWC6323 achieves optimal efficiency, specifically at low- and mid-range power levels where the PA typically operates, thereby dramatically increasing handset talk-time. Its built-in voltage regulator eliminates the need for external switches. This PA has built-in directional couplers for each band, with a common coupler output port CPL_OUT. The 3 mm x 5 mm x 1 mm surface mount package incorporates matching networks optimized for output power, efficiency and linearity in a 50 Ω system.
