A compact filtering power divider/combiner using surface acoustic wave (SAW) technology for low frequency applications is presented. The proposed power divider/combiner is based on parallel connected SAW coupled resonator filters providing a dual functional capability as well as a higher level of miniaturization. The designed structure is a 3 way power divider/combiner that exhibits a passband-filtering...
Power dividers/combiners are used as fundamental unit for power combining/splitting in different RF/Microwave circuits such as power amplifier modules, antenna array feeds or mixers. Most common types are based on quarter wave transmission line and their miniaturization is challenging especially in frequency less than GHz range where they exhibit very large physical size that make their use impractical...
A novel reconfigurable impedance matching network suitable for tunable RF front-ends is presented. The network is based on a transmission line loaded with 8 dual state MEMS capacitive and inductive devices and achieves 256 different impedance states. The application of both the capacitive and inductive elements results in a more uniformly distribution of the impedance states on the Smith chart compared...
