artifact description
Skyworks Inc. has sponsored a WPI Major Qualifying Project involving the design of a tunable filter for the radio-frequency (RF) section of a smartphone. Our project involves designing and analyzing a single bandpass filter that can be tuned to various center frequencies. The band of frequencies that will be considered include frequencies in cellular band 25 (1850 MHz – 1955 MHz). The design realized in this project uses lumped element components configured in a capacitive coupled chebychev filter topology.
