چکیده

A resonator using shear waves of lithium niobate is used in this paper to achieve large fractional bandwidth BAW filter. Electromechanical couplings in the 20–50 % range are obtained for the shear waves of a thin layer of Lithium Niobate suspended on a silicon substrate. By this way a filter with fractional bandwidth over 20% has been designed for space applications.

A Modified Lattice Configuration Design for Compact Wideband Bulk Acoustic Wave Filter Applications

High-performance bulk acoustic wave (BAW) filters have been widely applied in the advanced radio frequency (RF) wireless communication systems in the past decade. However, the demand for filters with large bandwidth, up to 10%, still puts a significant stress on the typical aluminum nitride (AlN)-based BAW filters. In this work, a modified lattice configuration is proposed to achieve a wideband...

Improvement on Diversity Gain with Filter Bandwidth Enlargement in Fractional Sampling OFDM Receiver

A diversity scheme with Fractional Sampling (FS) in an OFDM receiver has been investigated recently. Through FS, it is possible to separate multipath components and obtain diversity gain in OFDM systems. Enlargement of the bandwidth of the total frequency response between transmit and receive baseband filters allows the FS scheme to achieve path diversity. However, the transmit filter has to be...

Adjustable Fractional-Delay Filters Utilizing the Farrow Structure and Multirate Techniques

The Farrow structure can be used for efficient realization of adjustable fractional-delay FIR filters, but despite its efficiency compared to other approaches, its implementation complexity grows rapidly as the bandwidth approaches π. To reduce the complexity, a multirate approach has been proposed. In this approach, the input signal is first interpolated by a factor of two via the use of a fix...
