摘要: A multi-mode multi-band power amplifier (PA) module is described. In an exemplary design, the PA module includes multiple power amplifiers, multiple matching circuits, and a set of switches. Each power amplifier provides power amplification for its input signal when selected. Each matching circuit provides impedance matching and filtering for its power amplifier and provides a respective output signal. The switches configure the power amplifiers to support multiple modes, with each mode being for a particular radio technology. Each power amplifier supports at least two modes. The PA module may further include a driver amplifier and an additional matching circuit. The driver amplifier amplifies an input signal and provides an amplified signal to the power amplifiers. The additional matching circuit combines the outputs of other matching circuits and provides an output signal with higher output power. The driver amplifier and the power amplifiers can support multiple output power levels.

摘要: The amount of signal propagation and moisture penetration and corresponding reliability problems due to moisture penetration degradation in an IC can be reduced by fabricating two seal rings with non-adjacent gaps. In one embodiment, the same effect can be achieved by fabricating a wide seal ring with a channel having offset ingress and egress portions. Either of these embodiments can also have grounded seal ring segments which further reduce signal propagation.
