Exploring Surface Acoustic Wave Transversal Filters on Heterogeneous Substrates for 5G N77 Band
IUS, 2022This work explores the design of large bandwidth acoustic filters for the 5G N77 band by combining transversal topology with surface acoustic wave (SAW) resonators based on heterogeneous substrates.

Acoustic surface-wave transversal filters
IEEE Transactions on Circuit Theory, 1973Some basic concepts of transversal filters are reviewed. Transversal-filter structures provide a conceptually simple way for obtaining a wide range of transfer functions. However, the practical realization of such filters has, in the past, required very complex or bulky circuits because of the necessary delay line and because of the many taps and ...

Automatic equalization using transversal filters
IEEE Spectrum, 1967The restriction that linear distortion imposes on the flow of information has been well known for some time. Consequently, means have been developed for reducing this distortion through the insertion of compensating linear devices. In the past this reduction has been achieved through the use of conventional lumped-parameter networks, quite static by ...

Microelectronics Reliability, 1979
Abstract The present day digital data modems consist of the binary transversal filter (BTF), and a number of logic gates. This paper derives the BTF transfer function from the operational block diagram using shift register as a delay unit. Results are examined particularly from the point of view of the three types of distortion (truncation, aliasing ...

Synthesis of Transversal Bandpass Filters on Stacked Rectangular $ H$ -Plane Waveguide Cavities
IEEE transactions on microwave theory and techniques, 2019In this paper, a new transversal configuration is presented for waveguide bandpass filters (BPFs) on stacked rectangular $ H$ -plane waveguide cavities. Different from the conventional ladder BPFs, cavities constituting the proposed transversal BPFs are

A Quantitative Approach for Direct Synthesis of Bandpass Filters Composed of Transversal Resonators
IEEE Transactions on Circuits and Systems - II - Express Briefs, 2019This brief aims to propose a quantitative approach for direct synthesis of bandpass filters (BPFs) composed of a few transversal resonators. In conventional synthesis of these BPFs, coupling coefficients between input/output port and resonators are ...

Coefficient Inaccuracy in Transversal Filtering
Bell System Technical Journal, 1979Coefficient inaccuracy in transversal filters is known to degrade the frequency response, particularly in stopband regions. The magnitude of the stopband degradation increases with the number of stages n, the length of the impulse response. A widely used formula for the error in frequency response is proportional to √n.

Proceedings of the IEEE, 1968
An off-axis optical cavity has been successfully used as a transversal filter in the frequency domain. With a tap spacing of ∼40 nanoseconds, a square wave frequency response has provided alternating pass and rejection bands ∼12.5 MHz wide.
