We offer Best-In-class Vectron® SAW Filters and Discrete Filters for Aviation, Defense, Communications, IoT and Automotive sectors, compatible with harsh temperature applications.

2019年4月4日 · Surface Acoustic Wave Filters or SAW Filters are compact, low-cost RF filters that can be used in a wide range of applications up to 3 GHz. SAW filters operate by converting electrical energy into acoustic or mechanical energy on a piezoelectric material.

2021年8月16日 · acoustic wave (SAW) filter is ideal for use in applications requiring filters from 10 MHz to 3 GHz. This white paper discusses the advantages, design criteria, and material choices

SAW filter对温度变化也敏感，性能随着温度升高变差。 TC(temperature compensated)-SAW filter就是为了改善温度性能，IDT上增加了保护涂层。 普通的SAW filter频率温度系数(TCF, temperature coefficient of frequency)大约-45ppm/oC左右，而 TC-SAW 大约-15到-25ppm/oC。

We are pleased to introduce our latest SAW filter series, covering a broad range of center frequencies from 460 MHz to 1,585 MHz. This expanded lineup supports key GNSS bands (L1, L2, L5) across multiple constellations, including GPS, GLONASS, Galileo, and BeiDou, as well as popular ISM frequencies (460/868/915 MHz and 2.4 GHz).

2024年6月18日 · 表面声波（saw）和体声波（baw）滤波器技术是无线通信中常用的两种声波滤波器技术。saw滤波器在低频范围内表现出色，而在高频应用中，baw滤波器特别是fbar滤波器则更为适合。fbar滤波器能够在高频下提供更好的带宽...

SAW (Surface Acoustic Wave) Filters are designed to remove unwanted frequencies from a circuit. Items in this family convert signal voltages into acoustic waves at one end of the device. These waves travel the length of quartz device at a specific frequency.

SAW filter technology is the realization of parts with reduced size and weight; hence, a lower cost than other filter technologies since the same type of process equipment that IC manufacturers rely upon can be adapted for use to manufacture a SAW product. This white paper will present some general SAW theory

SAW滤波器是声表面波（Surface Acoustic Wave）滤波器的简称，其本质是采用石英晶体、压电陶瓷等压电材料，利用其压电效应和声表面波传播的物理特性而制成的一种滤波专用器件，广泛应用于电视机及录像机中频电路中以取代LC中频滤波器，使图像、声音的质量 ...

RSF 系列的 LoRa SAW 滤波器提高了选择性，并抑制了 433 MHz、868 MHz 或 915 MHz 指定频段之外的杂散或有害信号。 SAW 滤波器具有低插入损耗，低幅度和群延迟纹波，小尺寸和高带外抑制特性。
