J www.fairchildsemi.com RMPA1965 US-PCS CDMA, CDMA2000-1X and WCDMA PowerEdgeTM Power Amplifier Module Efficiency Improvement Applications In addition to high-power/low-power bias modes, the efficiency of the PA module can be significantly increased at backed-off RF power levels by dynamically varying the supply voltage (Vcc) applied to the amplifier. Since mobile handsets and power amplifiers frequently operate at 10-20 dB back-off, or more, from maximum rated linear power, battery life is highly dependent on the DC power consumed at antenna power levels in the range of 0 to +16dBm. The reduced demand on transmitted RF power allows the PA supply voltage to be reduced for improved efficiency, while still meeting linearity requirements for CDMA modulation with excellent margin. High-efficiency DC-DC converters are now available to implement switched-voltage operation. With the PA module in low-power mode (Vmode = +2.0V) at+16dBm output power and supply voltages reduced from 3.4V nominal down to 1.2V, power-added efficiency is more than doubled from 9.5 percent to nearly 25 percent (Vcc = 1.2V) while maintaining a typical ACPR1 of -52dBc and ACPR2 of less than -61dBc. Operation at even lower levels of Vcc supply voltage are possible with a further restriction on the maximum RF output power.

J www.fairchildsemi.com RMPA1965 US-PCS CDMA, CDMA2000-1X and WCDMA PowerEdgeTM Power Amplifier Module Applications Information CAUTION: THIS IS AN ESD SENSITIVE DEVICE. Precautions to Avoid Permanent Device Damage: * Cleanliness: Observe proper handling procedures to ensure clean devices and PCBs. Devices should remain in their original packaging until component placement to ensure no contamination or damage to RF, DC and ground contact areas. * Device Cleaning: Standard board cleaning techniques should not present device problems provided that the boards are properly dried to remove solvents or water residues. * Static Sensitivity: Follow ESD precautions to protect against ESD damage: - A properly grounded static-dissipative surface on which to place devices. - Static-dissipative floor or mat. - A properly grounded conductive wrist strap for each person to wear while handling devices. * General Handling: Handle the package on the top with a vacuum collet or along the edges with a sharp pair of bent tweezers. Avoiding damaging the RF, DC, and ground contacts on the package bottom. Do not apply excessive pressure to the top of the lid. * Device Storage: Devices are supplied in heat-sealed, moisture-barrier bags. In this condition, devices are protected and require no special storage conditions. Once the sealed bag has been opened, devices should be stored in a dry nitrogen environment. Device Usage: Fairchild recommends the following procedures prior to assembly. * Assemble the devices within 7 days of removal from the dry pack. * During the 7-day period, the devices must be stored in an environment of less than 60% relative humidity and a maximum temperature of 30C * If the 7-day period or the environmental conditions have been exceeded, then the dry-bake procedure, at 125C for 24 hours minimum, must be performed. Solder Materials & Temperature Profile: Reflow soldering is the preferred method of SMT attachment. Hand soldering is not recommended. Reflow Profile * Ramp-up: During this stage the solvents are evaporated from the solder paste. Care should be taken to prevent rapid oxidation (or paste slump) and solder bursts caused by violent solvent out-gassing. A maximum heating rate is 3C/sec. * Pre-heat/soak: The soak temperature stage serves two purposes; the flux is activated and the board and devices achieve a uniform temperature. The recommended soak condition is: 60-180 seconds at 150-200C. * Reflow Zone: If the temperature is too high, then devices may be damaged by mechanical stress due to thermal mismatch or there may be problems due to excessive solder oxidation. Excessive time at temperature can enhance the formation of inter-metallic compounds at the lead/board interface and may lead to early mechanical failure of the joint. Reflow must occur prior to the flux being completely driven off. The duration of peak reflow temperature should not exceed 20 seconds. Soldering temperatures should be in the range 255-260C, with a maximum limit of 260C. * Cooling Zone: Steep thermal gradients may give rise to excessive thermal shock. However, rapid cooling promotes a finer grain structure and a more crack-resistant solder joint. The illustration below indicates the recommended soldering profile. Solder Joint Characteristics: Proper operation of this device depends on a reliable void-free attachment of the heat sink to the PWB. The solder joint should be 95% void-free and be a consistent thickness. Rework Considerations: Rework of a device attached to a board is limited to reflow of the solder with a heat gun. The device should be subjected to no more than 15C above the solder melting temperature for no more than 5 seconds. No more than 2 rework operations should be performed.
