摘要
我们报告了标称1.2 W 2.5 GHz GaAs/AlGaAs HBT单元放大器的双温度射频偏置应力测试。在标称输入偏置下,在Tj=218/spl℃和245/spl℃/C下,分别获得了2020和1340小时的mttf。估计活化能为0.42 eV,与已发表的类似器件在直流偏置应力下的结果一致。
Reliability of self-aligned, ledge passivated 7.5 GHz GaAs/AlGaAs HBT power amplifiers under RF bias stress at elevated temperatures
We report a two-temperature RF bias stress test on nominal 1.2 W 2.5 GHz GaAs/AlGaAs HBT unit cell amplifiers. MTTFs of 2020 and 1340 hours were obtained at Tj=218/spl deg/C and 245/spl deg/C, respectively, under nominal input bias. An activation energy of 0.42 eV is estimated, consistent with published results for similar devices under DC bias stress.
