Description
The ACPM- 7051 is a multiband multimode PA which sup- ports GMSK and 8-PSK modulation schemes and UMTS bands 1 and 5. There are two amplifier chains, one is to support low band (GSM850/900 and UMTS Band5), and the other is to support high band (DCS1800/PCS1900 and UMTS band1). CoolPAM technology, Avago Technologies’ Power Ampli- fier technologies, provides extended talk time with ex - tremely low quiescent current and enhanced efficiency at low and medium power modes. Reliability Prediction Model Failure rate predictions are based on HTOL test results. The prediction uses an exponential cumulative failure function (constant failure rate) as the reliability predic - tion model to predict failure rate and mean time to failure (MTTF) at various temperatures as shown in Table 2. The wear out mechanisms is therefore not considered. The Arrhenius temperature de-rating equation is used. We as- sume no failure mechanism change between stresses and use conditions. Bias and temperature are alterable stress- es and must be considered with the thermal resistance of the devices when determining the stress condition. The failure rate will have a direct relationship to the life stress. The failure rate prediction was calculated using activation energy of 1.58eV as a conservative estimate. Confidence intervals are based upon the chi-squared prediction method associated with exponential distribution. Table 1. Life prediction: Table 2. Estimated for Various Channel Temperatures are as follows:

MM Class A is ESD voltage level <200V, Class B is voltage level between 200V and 400V, Class C is voltage level > 400V. ESD Sensitivity Note: ESD Sensitivity Level for Human Body Model and Machine Model necessitate the following handling pre - cautions: 1. Ensure Faraday cage or conductive shield bag is used during transportation processes, 2. If the static charge at SMT assembly station is above device sensitivity level, place an ionizer near to the device for charge neutralization purposes. 3. Personal grounding must be worn at all times when handling the devices. CDM Class I <200 volts, Class II 200 to <500 volts, Class III 500 to 1000 volts, Class IV >1000 volts Moisture Sensitivity Classification: Level 3\` Preconditioning per JESD22-A113-D Level 3 was per - formed on all devices prior to reliability testing except ESD and mechanical tests MSL3 Preconditioning (JESD22-A113D): 125 °C HTSL for 24hrs + 60°C/60%RH for 40hrs + 3XIR Reflow, 260°C peak.
