Design and Multipactor Analysis of an X-Band Quarter-Wavelength Two-Section Coaxial Stepped-Impedance Resonator Filter for High-Power Applications

2026

Abstract

A two-pole filter based on a quarter-wavelength, two-section coaxial stepped-impedance resonator (SIR) in volumetric technology is reported at X-band, targeting scientific and military applications requiring high power handling (PH). Topological limitations of the SIR structure are analyzed across all degrees of freedom for spurious-response suppression. A multipactor (MP) study predicts a PH threshold of 247 W in a radio-frequency (RF) volume of 1.6 cm3, confirming suitability of the proposed design for high-power X-band operation. An aluminum prototype was manufactured in two parts using CNC machining. Simulations and measurements are presented and discussed.

Electronic filter

Electronic filters are a type of signal processing filter in the form of electrical circuits. This article covers those filters consisting of lumped electronic components, as opposed to distributed-element filters. That is, using components and interconnections that, in analysis, can be considered to exist at a single point. These components can be in discrete packages or part of an integrated circuit. Electronic filters remove unwanted frequency components from the applied signal, enhance wanted ones, or both.

Chebyshev filter

Chebyshev filters are analog or digital filters that have a steeper roll-off than Butterworth filters, and have either passband ripple (type I) or stopband ripple (type II). Chebyshev filters have the property that they minimize the error between the idealized and the actual filter characteristic over the operating frequency range of the filter, but they achieve this with ripples in the passband. This type of filter is named after Pafnuty Chebyshev because its mathematical characteristics are derived from Chebyshev polynomials.

Analogue filter

Analogue filters are a basic building block of signal processing much used in electronics. Amongst their many applications are the separation of an audio signal before application to bass, mid-range, and tweeter loudspeakers; the combining and later separation of multiple telephone conversations onto a single channel; the selection of a chosen radio station in a radio receiver and rejection of others.
