Abstract in another language

In this work, the thermal effects on a tunable matching network (TMN) based on micro electro mechanical system (MEMS) are investigated. A capacitive MEMS switch acts as the active component in a TMN that provides reconfigurability on the PA architecture. However, the large signal operation of the PA causes the membrane of the MEMS switch to heat up, leading to variations of its intrinsic characteristics. These effects are modeled and their influence on the linearity of the PA addressed. The study is aided by a behavioral model of the capacitive MEMS switch with the additional modeling of the thermal effects that raise due to power dissipation at the MEMS’s membrane. The PA architecture is based on a commercial process design kit for the PA and the geometrical and material characteristics of an available MEMS switch.
