RF SIGNAL MULTIPLEXING DEVICE HAVING WINDOW STRUCTURE

摘要

PURPOSE: An RF signal multiplexing device with a window structure is provided to reduce a signal modulation distortion by forming a window between a first resonator and a second resonator. CONSTITUTION: A first filter includes multiple first resonators(312a,312n). A second filter includes multiple second resonators(314a,314n). An extension unit(316) is extended from one of the first resonators. An RF signal is coupled with the second resonator through the extension unit. A window is formed between the first resonator and the second resonator.
