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 Lowpower (LowBiasMode) +7.5 dBm Low +1.8 V +1.8 V +1.8 V 3.1 - 4.35 V > 3.1 V Medpower (MediumBiasMode) >+6.5dBm +17 dBm Low +1.8 V +1.8 V 0V 3.1 - 4.35 V > 3.1 V Highpower (HighBiasMode) >+16dBm 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 2.2µF C1 C9 0.01 µF 100pF GNDatslug 1 2 RFIN VMODE2 VMODE1 VEN VBATT VCC RFIN RFOUT 10 C3 330pF 9 3 VMODE2 CPLIN 8 4 VMODE1 GND 7 5 VEN CPLOUT 6 C2 C4 0.01 µF 2.2µFceramic RFOUT CPLIN CPLOUT Figure 10: Evaluation Board Schematic Data Sheet - Rev 2.1 08/2011 7 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 2.1 08/2011 ALT6708 COMPONENT PACKAGING Pin 1 Figure 13: Tape & Reel Packaging Table 6: Tape & Reel Dimensions PACKAGETYPE TAPEWIDTH POCKETPITCH REEL CAPACITY MAX REEL DIA 3 mm x 3 mm x 1 mm 12 mm 4 mm 2500 7" Data Sheet - Rev 2.1 08/2011 9 ALT6708 ORDERING INFORMATION ORDER NUMBER TEMPERATURE RANGE PACKAGE DESCRIPTION ALT6708RM45Q7 -30 oC to +90 oC RoHS Compliant 10 Pin 3 mm x 3 mm x 1 mm TapeandReel,2500piecesperReel SurfaceMountModule ALT6708RM45P9 -30 oC to +90 oC RoHS Compliant 10 Pin 3 mm x 3 mm x 1 mm Partial Tape and Reel SurfaceMountModule COMPONENTPACKAGING ANADIGICS, Inc. 141 Mount Bethel Road Warren, New Jersey 07059, U.S.A.
