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 VCC to both power amplifiers and simplify control with a common V MODE pin. The device is manufactured on an advanced InGaP HBT MMIC technology offering state-of-the-art reliability, temperature stability, and ruggedness. The AWT6321 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 a costly external DAC or DC-DC converter. Through selectable bias modes, the AWT6321 achieves optimal efficiency across different output power levels, specifically at low- and midrange power levels where the PA typically operates, thereby dramatically increasing handset talk-time and standby-time. Its built-in voltage regulator eliminates the need for external switches. 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. 10/2008 Figure 1: Block Diagram AWT6321 Figure 2: Pinout Table 1: Pin Description PIN NAME DESCRIPTION 1 VEN_CELL Enable Voltage for Cell Band 2 RFIN_CELL RF Input for Cell Band 3 VMODE Mode Control Voltage for Cell and PCS Bands 4 VBATT Battery Voltage 5 N/C No Connection 6 RFIN_PCS RF Input for PCS Band 7 VEN_PCS Enable Voltage for PCS Band 8 RFOUT_PCS 9 GND Ground 10 GND Ground 11 VCCA Battery Voltage A 12 VCC 13 14 2 RF Output for PCS Band Supply Voltage RFOUT_CELL RF Output for Cell Band GND Ground Data Sheet - Rev 2.2 10/2008 AWT6321 ELECTRICAL CHARACTERISTICS Table 2: Absolute Minimum and Maximum Ratings PARAMETER MIN MAX UNIT Supply Voltage (VBATT, VCC, VCCA) 0 +5 V Mode Control Voltage (VMODE) 0 +3.5 V Enable Voltage (VEN_CELL, VEN_PCS) 0 +3.5 V RF Input Power (PIN) - +10 dBm -40 +150 °C Storage Temperature (TSTG) Stresses in excess of the absolute ratings may cause permanent damage.
