The Bias Control table below lists the recommended modes of operation for various applications. Shutdown Mode The power amplifier may be placed in a shutdown mode by applying logic low levels (see Operating Ranges table) to the VEN, VMODE1 and VMODE2 voltages. Three operating modes are recommended to optimize current consumption. High Bias/High Power operating mode is for POUT levels > 16 dBm. At ~17dBm - 6.5 dBm, the PA should be "Mode Switched" to Medium Power Mode. For POUT levels < ~7.5 dBm, the PA can be switched to Low Power Mode for even lower quiescent current consumption. Bias Modes The power amplifier may be placed in either Low, Medium or High Bias modes by applying the appropriate logic level (see Operating Ranges table) Table 6: Bias Control POUT LEVELS BIAS MODE VEN VMODE1 VMODE2 vcc VBATT Low power (Low Bias Mode) +7.5 dBm Low +1.8 V +1.8 V +1.8 V 3.1 - 4.35 V > 3.1 V Med power (Medium Bias Mode) > +6.5 dBm +17 dBm Low +1.8 V +1.8 V 0V 3.1 - 4.35 V > 3.1 V High power (High Bias Mode) > +16 dBm High +1.8 V 0V 0V 3.1 - 4.35 V > 3.1 V - Shutdown 0V 0V 0V 3.1 - 4.35 V > 3.1 V APPLICATION Shutdown VBATT VCC C5 2.2 F C1 C9 0.01 F 100 pF GND at slug 1 2 RFIN VMODE2 VMODE1 VEN VBATT VCC RFIN RFOUT 10 9 3 VMODE2 CPLIN 8 4 VMODE1 GND 7 5 VEN CPLOUT 6 Figure 10: Evaluation Board Schematic 7 Data Sheet - Rev 2.3 03/2012 C3 330 pF C2 C4 0.01 F 2.2 F ceramic RFOUT CPLIN CPLOUT ALT6708 PACKAGE OUTLINE Figure 11: M45 Package Outline - 10 Pin 3 mm x 3 mm x 1 mm Surface Mount Module Pin 1 Identifier Date Code (YYWW) 6708R LLLLNN YYWWCC Part Number Lot Number Country Code(CC) Figure 12: Branding Specification - M45 Package 8 Data Sheet - Rev 2.3 03/2012 ALT6708 PCB AND STENCIL DESIGN GUIDELINE Figure 13: Recommended PCB Layout Information 9 Data Sheet - Rev 2.3 03/2012 ALT6708 COMPONENT PACKAGING Pin 1 Figure 14: Carrier Tape Figure 15: Reel 10 Data Sheet - Rev 2.3 03/2012 ALT6708 ORDERING INFORMATION ORDER NUMBER TEMPERATURE RANGE PACKAGE DESCRIPTION ALT6708RM45Q7 -40 oC to +90 oC RoHS Compliant 10 Pin 3 mm x 3 mm x 1 mm Tape and Reel, 2500 pieces per Reel Surface Mount Module ALT6708RM45P9 -40 oC to +90 oC RoHS Compliant 10 Pin 3 mm x 3 mm x 1 mm Partial Tape and Reel Surface Mount Module COMPONENT PACKAGING ANADIGICS, Inc. 141 Mount Bethel Road Warren, New Jersey 07059, U.S.A.
