A carrier-burst transmitter implementation: Design of bandpass filter and amplifier-BPF connection

2012 Workshop on Integrated Nonlinear Microwave and Millimetre-wave Circuits, 2012
The importance of the bandpass reconstruction filter, BPF, in the proper operation of carrier-burst transmitters is widely accepted. However, it is often analyzed as if it could be considered isolated from the other system's components. To fill this gap, this paper presents a detailed study of the carrier-burst transmitter BPF, addressing both its most

Compact cascaded quadruplet bandpass filter (CQ-BPF) using folded loop resonator with via-hole

2011 IEEE International RF & Microwave Conference, 2011
A compact cascaded quadruplet bandpass filter (CQ-BPF) using short-circuited loop resonators is proposed for size reduction. The short-circuited loop has a resonance at a half wavelength by utilizing a via-hole and is modified to a folded structure to reduce a loop size.

Power distribution to multiple implanted sensor devices using a multiport bandpass filter (BPF) approach

2014 IEEE MTT-S International Microwave Symposium (IMS2014), 2014
This paper presents a magnetically coupled bandpass filter (BPF) approach for power distribution to multiple implanted devices. The BPF design approach accounts for the multiple loads and enables maximum power transfer into each individual receiver for given coupling coefficients between the coils.

High frequency performance and compact LTCC bandpass filter (BPF) with three transmission zeros

2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE), 2017
In this paper, a design of compact LTCC bandpass filter with three layers and three Transmission Zeros (TZs) is proposed, which obtain a high skirt selectivity with narrow passband and wide stopband. The mixed Electric and Magnetic (EM) coupling and Source-Load (S-L) coupling are utilized to create TZs in this design.

Investigation into microstrip dual-mode bandpass filters (BPFS) with in-line feed-line configurations

Microwave and Optical Technology Letters, 2006
Based on the geometry relationship of the conventional dual-mode ring resonators, this study concisely describes the operation principle of a kind of dual-mode resonator filters with in-line feed-lines. The investigated filter topology is fed by two pairs of orthogonal branch lines and can realize in-line configuration for the input and output (I/O ...

Bandpass filter (BPF) design using waveguide iris conformation over Substrate Integrated Waveguide (SIW) Bend

2017 1st International Conference on Electronics, Materials Engineering and Nano-Technology (IEMENTech), 2017
In this paper a novel Substrate Integrated Waveguide(SIW) filter has been proposed, bended with 150° angle and loaded with cylindrical iris for obtaining the filtering characteristic in the range of Ku band. 150°bend within the SIW structure is provided to facilitate its integration ability over planar Microwave Integrated Circuits (MICs).

Compact LTCC Bandpass Filter (BPF) with High Frequency Selectivity Based on Mixed Electric and Magnetic Coupling

2019 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2019
In this paper, based on mixed electronic and magnetic coupling (E-M coupling) structures and miniaturized resonator units, a compact low-temperature co-fired ceramic (LTCC) bandpass filter at 2.48 GHz is proposed. Due to the E-M coupling and source-loading structures, three transmission zeros (TZs) are introduced.

Synthesis and design of four pole ultra-wide band (UWB) bandpass filter (BPF) employing multi-mode resonators (MMR)

2012 IEEE/MTT-S International Microwave Symposium Digest, 2012
A complete synthesis and design of fourth order UWB BPF has been presented in this paper. Based on MMR, equivalent circuit is used to derive transfer function which is then used to extract the filtering function. For optimal solution, mathematical formulation is used to calculate characteristic impedance of filter in order to have chebyshev type ...
