This HELP3DCTM PA can be used with an external switch mode power supply (SMPS) to improve its efficiency and reduce current consumption further at medium and low output powers. A “daisy chainable” directional coupler is integrated in the module thus eliminating the need of external couplers. The device is manufactured on an advanced InGaP HBT MMIC technology offering state-of-the-art reliability, temperature stability, and ruggedness. There are two selectable bias modes that optimize efficiency for different output power levels, and a shutdown mode with low leakage current, which increases handset talk VBATT 1 RFIN 2 VMODE2 (N/C) 3 VMODE1 VEN 02/2012 10 VCC 9 RFOUT 8 CPLIN 4 7 GND 5 6 CPLOUT CPL Bias Control Voltage Regulation Figure 1: Block Diagram AWT6638 VBATT 1 10 RFIN 2 9 RFOUT VMODE2 (N/C) 3 8 CPLIN VMODE1 4 7 GND VEN 5 6 CPLOUT Figure 2: Pinout (X-ray Top View) Table 1: Pin Description PIN NAME DESCRIPTION 1 VBATT Battery Voltage 2 RFIN RF Input 3 2 VMODE2 (N/C) No Connection Mode Control Voltage 1 4 VMODE1 5 VEN 6 CPLOUT 7 GND Ground 8 CPLIN Coupler Input 9 RFOUT RF Output 10 VCC PA Enable Voltage Coupler Output Supply Voltage PRELIMINARY DATA SHEET - Rev 1.3 02/2012 VCC AWT6638 ELECTRICAL CHARACTERISTICS Table 2: Absolute Minimum and Maximum Ratings PARAMETER MIN MAX UNIT Supply Voltage (VCC) 0 +5 V Battery Voltage (VBATT) 0 +6 V Control Voltages (VMODE1, VENABLE) 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.

Bias Modes The power amplifier may be placed in either a Low Bias mode or a High Bias mode by applying the appropriate logic level (see Operating Ranges table) to VMODE1. The Bias Control table lists the recommended modes of operation for various applications. VMODE2 is not necessary for this PA. Two operating modes are available to optimize current consumption. High Bias/High Power operating mode is for POUT levels > 16 dBm. At around 17 dBm output power, the PA can be “Mode Switched” to Low power mode for lowest quiescent current consumption.

The PA is designed to operate up to 17 dBm in the low power mode, thus eliminating the need for three gain state, while still maintaining low quiescent current and high efficiency in low and medium power levels. Average weighted efficiency can be increased by using an external switch mode power supply (SMPS) or DC/DC converter to reduce VCC. The directional “daisy chainable” coupler is integrated within the PA module, therefore there is no need for external couplers. The AWT6638 has an integrated voltage regulator, which eliminates the need for an external constant voltage source. The PA is turn on/off is controlled by VEN pin. A single VMODE control logic (VMODE1) is needed to operate this device. AWT6638 requires only two calibration sweeps for system calibration, thus saving calibration time. Figure 11 shows one application example on mobile board. C1 and C2 are RF bypass caps and should be placed nearby pin 1 and pin 10. Bypass caps C4 and C5 may not be needed. Also a “T” matching topology is recommended at PA RFIN and RFOUT ports to provide matching between input TX Filter and Duplexer / Isolator.
