RM008
PA Module for Dual-band GSM900 and DCS1800 Applications
The RM008 is a dual-band Power Amplifier Module (PAM) designed in a compact form factor for Class 4 GSM900 and Class 1 DCS1800 operation. The PAM consists of two Gallium Arsenide (GaAs) Heterojunction Bipolar Transistor (HBT) power amplifiers and internal components that match the RF input and output ports to 50 ohms, which reduces the number of external components for a dual-band design. Optimized for lithium-ion battery operation, both PAs share common power supply pins to distribute current. The RM008 dual PAM has extremely low standby current, which maximizes handset standby time. A block diagram of the RM008 is shown below. The Analog Power Control (APC) pins (GSM APC and DCS APC), control output power level. Table 4 of this data sheet shows the complete signal pin assignments and descriptions of the RM008 dual-band Power Amplifier Module.

Package and Handling Information
Package and Handling Information
Because of its sensitivity to moisture absorption, this device package is baked and vacuum packed prior to shipment. Instructions on the shipping container label must be followed regarding exposure to moisture after the container seal is broken, otherwise, problems related to moisture absorption may occur when the part is subjected to high temperature during solder assembly. The RM008 is capable of withstanding an MSL 3/240 C solder reflow. Care must be taken when attaching this product, whether it is done manually or in a production solder reflow environment. If the part is attached in a reflow oven, the temperature ramp rate should not exceed 5 C per second; maximum temperature should not exceed 240 C. If the part is manually attached, precaution should be taken to insure that the part is not subjected to temperatures exceeding 240 C for more than 10 seconds. For details on both attachment techniques, precautions, and handling procedures recommended by Skyworks, please refer to Application Note: PCB Design and SMT Assembly/Rework, Document Number 101752. Additional information on standard SMT reflow profiles can also be found in the JEDEC Standard J-STD-020A.

Electrostatic Discharge Sensitivity
Electrostatic Discharge Sensitivity
The RM008 is a Class I device. Figure 6 lists the Electrostatic Discharge (ESD) immunity level for each pin of the RM008 product. The numbers in Figure 6 specify the ESD threshold level for each pin where the I-V curve between the pin and ground starts to show degradation. The ESD testing was performed in compliance with MIL-STD-883E Method 3015.7 using the Human Body Model. Since 2000 volts represents the maximum measurement limit of the test equipment used, pins marked > 2000 V pass 2000V ESD stress.

Various failure criteria can be utilized when performing ESD testing. Many vendors employ relaxed ESD failure standards which fail devices only after "the pin fails the electrical specification limits" or "the pin becomes completely non-functional". Skyworks employs most stringent criteria, fails devices as soon as the pin begins to show any degradation on a curve tracer. To avoid ESD damage, both latent and visible, it is very important that the product assembly and test areas follow the Class-1 ESD handling precautions listed in Table 5.
