A wideband circularly polarized (CP) dielectric resonator antenna (DRA) with filtering
response was proposed in this communication. To combine additional filtering and harmonic …

Bandpass power amplifiers (PAs) are typically implemented by a cascade of second-order
topologies. To achieve a wide and flat passband response, the number of resonators must …

In this article, a single-ended filtering impedance transformer with good frequency selectivity
and high transforming ratio is proposed at first, comprising of the two cascaded coupled-line …

In this brief, a power amplifier (PA) with excellent integrated filtering characteristics is
presented. The designed process is based on a novel impedance transformer (IT) consisting …

The design and performance of a WR-5 band 135-150-GHz Schottky diode-based frequency
tripler which uses waveguide resonator filters for low loss impedance matching is presented …

In this paper, a class of short-ended coupled-line impedance transformers with ultrahigh
transforming ratio is proposed. The principle for the realization of such an ultrahigh …

A class of impedance transformers on coupled lines and multisection stepped-impedance
transmission line are presented in this paper, which can achieve a wide operating band or …

In this brief, a novel filtering impedance transformer with good selectivity and high
termination impedance is proposed, of which close‐formed design equations are derived …

A new synthesis for the design of a bandpass filter (BPF) with arbitrary real and/or complex
termination impedances is presented in this paper. The proposed BPF can be terminated …

This article presents a novel frequency selective impedance transformer (ITs) with high
transforming ratio and extremely low/high termination impedances (1 Ω or 2 Ω and several …
