Abstract Microwave photonic filters have been regarded as an alternative to traditional radio‐frequency because of their wide bandwidth and large tunability. Integrated microwave can integrate all necessary components into a single chip are highly demanded for future applications. Here, integrated frequency‐tunable bandpass filter based on silicon platform is proposed demonstrated. The consists...

In circuit quantum electrodynamics, qubits are typically measured using dispersively coupled readout resonators. Coupling between each resonator and its electrical environment, however, reduces the qubit lifetime via Purcell effect. Inserting a filter counters this effect while maintaining high fidelity but measurement bandwidth and, thus, limits multiplexing capacity. Letter, we develop implem...

A compact ultra-wideband (UWB) bandpass filter (BPF) with wide passband using defected ground structure (DGS) is proposed. The proposed UWB filter is constructed by cascading a high pass filter (HPF) and a lowpass filter (LPF). HPF with short-circuited stubs is used to realize the lower stopband and a LPF is used to attenuate the upper stopband. In order to make the filter size compact, DGS tec...

Dual band bandpass filter is designed and optimized for RF wireless applications. The performances of that RF dual band filter are improved especially parameters describing the insertion loss, return losses and rejection. Dual band bandpass filter using stub loaded resonators is designed and characterized. Theoretical results are compared with experimental data. This comparison shows that the m...

In this letter, a design of Compact Ultra-Wideband (UWB) bandpass filter with a switchable notch band for WLAN (5.3-5.9GHz) interference rejection is proposed. As 5.3-5.9GHz wireless local area network (WLAN) is existed in UWB spectrum range (3.1 -10.6GHz) and may interfere with UWB system operation. The UWB bandpass filter is implemented using a basic multiple mode resonator (MMR) structure fe...
