The use of multi-band microwave systems is increasing, especially for cellular networks. Many cell phones today can transmit different types of coded signals over multiple frequency bands. Radio frequency filters are essential devices in the communication of these signals. With a proper multi-band filter design, a two terminal device can be made that performs the needed filtering for the multiple frequency bands used by a cell phone or by base stations. This reduces the amount and total size of the filters and eliminates the need for switches and multiple chip sets for each type of transmitted signal.

多频段微波系统的使用正在增加，特别是对于蜂窝网络。如今许多手机可以通过多个频段传输不同类型的编码信​​号。射频滤波器是这些信号通信中必不可少的设备。通过适当的多频带滤波器设计，可以制造两个终端设备，对手机或基站使用的多个频带执行所需的滤波。这减少了滤波器的数量和总尺寸，并且消除了针对每种类型的传输信号的开关和多个芯片组的需要。
