型号 BAND-PASS FILTER 产品简介太赫兹带通滤波器用于选择太赫兹波范围内的设定频率。THz滤滤器可用于各种应用,包括实验室和空间研究。这种高性能太赫兹滤波器一般由4-6层单片太赫兹滤波片组成,可以将带外的杂散太赫兹波能量降低到非常底的水平,通俗的讲就是相比常规的单片的太赫兹带通滤波片,这种多层高性能太赫兹带...
In the present chapter, bandpass filter in THz spectra is designed using defected one-dimensional structure where the central wavelength is chosen at 1550nm. Double negative index materials, i.e. metamaterials are considered for filter design which is already a proved candidate for providing better ...
The proposed solution allows to easily manufacture many such filters in a single piece of metal foil forming a filter bank without increasing the price of the element. 展开 关键词: Submillimeter wave measurements Bandpass filters Distributed parameter filters Submillimeter wave filters Spectroscopy ...

(~15 cm) RF electrical cable. A 1-mm to WR-10 waveguide transition was used to connect cable to a WR-10 electrical bandpass filter (mi-wave 460W-86/94/387) with 8 GHz bandwidth and central frequency 90 GHz. The filtered signal was then amplified with an amplifier (mi-wave ...
After amplification and bandpass filtering to reduce the amplified spontaneous emission noise (not shown in Fig. 8), the signal is fiber connected to the receiver. At the receiver, a single Mach–Zehnder modulator (MZM) is used for the demultiplexing. Another AWG generates the unmodulated HG0-...
