... MHz, 880 to 915 MHz, 1710 to 1785 MHz and 1850 to 1910 MHz. DESCRIPTION The BGY284 is a power amplifier module in a SOT775 surface mounted package with a plastic cap. The module consists of two separated line-ups, one for low band (LB,GSM850/EGSM900) and one for high band (HB, DCS1800/PCS1900) with internal power detection function, power control loop, input and output matching ...

... For every line-up the power amplifier block generates a detected output power signal, that is an input to the power control block. Control logic In the control logic block the various signals are generated to control the complete BGY284 out of V indicated in the mode control table. The V in idle mode and the battery current consumption is almost zero. ...

... SOLDERING RECOMMENDATIONS Reflow profile: The BGY284 is a laminate based PA module in a LGA package. The module can be assembled using a standard SMT reflow process in a convection or IR-oven. In the graph below (see Fig.8) the minimum and maximum limits of the temperature profile are given. The actual profile has to be within these limits, and will depend on the PCB material, the number and size of the components to be assembled, and the type of solder which is being used ...

... If a thinner or thicker stencil is being used, the dimensions of the stencil apertures have to be adjusted. Moisture sensitivity level: The BGY284 is tested according to the JEDEC standard JESD 22-A113C. The BGY284 is classified on MSL3 for a lead containing soldering profile with a peak temperature of 240 C, and on MSL4 for a lead free soldering profile with a peak temperature of 260 C. ...
