Abstract: Device and a method of forming an integrated circuit (IC) that offers protection against ESD in RE applications is disclosed. The device includes a transmission line (TL) coupled to a signal pad. The TL is a short circuited stub that is configured as an ESD protection device and as a band pass filter in dependence of a center frequency of the band pass filter. The TL is configured to pass through a signal in response to a frequency of the signal being within an allowable range of frequencies of the band pass filter. The TL functioning as an ESD protection device is configured to shunt the signal in response to the frequency being outside the allowable range. The IC may include an array of control switches that are operable to change an electrical length L of the TL. The center frequency is tunable by controlling the electrical length L.

Abstract: A flat cable high-frequency filter includes a dielectric substrate extending in a transmission direction of a high-frequency signal. The dielectric substrate includes dielectric layers stacked on each other. Elongated conductor patterns are provided on a flat surface of one dielectric layer which faces another dielectric layer. The conductor patterns are as wide as possible in the dielectric substrate in accordance with a desired inductance. A capacitive coupling conductor pattern opposes one conductor pattern by a predetermined area with a dielectric layer therebetween. By using a connecting conductor, the capacitive coupling conductor pattern is connected to the conductor pattern which does not oppose the capacitive coupling conductor pattern.

Abstract: The present invention related to self-limiting filters, arrays of such filters, and methods thereof. In particular embodiments, the filters include a metal transition film (e.g., a VO2 film) capable of undergoing a phase transition that modifies the film's resistivity. Arrays of such filters could allow for band-selective interferer rejection, while permitting transmission of non-interferer signals.
