Description
Reliability Prediction Model
The AFEM-9040 is a multiband multimode module that
includes PAs, duplexers, ANT switch, and coupler. This module
supports GMSK and 8-PSK modulation schemes, UMTS/LTE
bands 1, 2/25, 3, 4, 34, and 39, and CDMA BC1. The AFEM-9040
is designed to support ET (envelope tracking) for FDD bands
and APT (average power tracking) operation for TDD bands,
and the part can support CA (carrier aggregation) for B1+B3.
Failure rate predictions are based on HTOL test results. The
prediction uses an exponential cumulative failure function
(constant failure rate) as the reliability prediction model to
predict failure rate and mean time to failure (MTTF) at various
temperatures as shown in Table 2. The wear-out mechanisms
are therefore not considered. The Arrhenius temperature
de-rating equation is used. We assume no failure mechanism
change between stresses and use conditions. Bias and
temperature are alterable stresses 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 1.33eV as a conservative
estimate. Confidence intervals are based upon the chi-squared
prediction method associated with exponential distribution.
Input and output terminals are internally matched to 50 Ω. The
power amplifier is manufactured on an advanced InGaP HBT
technology offering state-of-the-art reliability, temperature
stability, and ruggedness. This module is housed in a costeffective, extremely small and thin 5.5 mm x 7.7 mm package.

Point typical MTTF is simply the total device hours divided by the number of failures. Since no failures were observed, the point estimate is calculated under
the assumption that one unit failed. FIT rates shown are relatively high due to the limited device hours at product release.
