White Band Space Using Filter

Because the white space band has the characteristics of highly free design, the development RF engineer or research engineer can freely open the desired frequency band and specifications in Bandwidth, Attenuation value, Power, etc. In order to allow RF engineers to conduct research fully freely, Temwell group provides the adequately Custom RF Filter and Components in the world design service.

Temwell as worldwide expert in RF Filter and Microwave design and manufacture, set  the most complete RF development team, specializing in providing customized proposal and design of various RF & Microwave Components in RF Transmission circuit , and providing one-stop service for worldwide clients.

Our professional design services, including customization of various specifications: frequency customization of all frequency bands in various regions, free adjustment of Bandwidth changes, Attenuation value that can be specified, and even specifications in size, power, Return Loss, Insertion Loss, V.S.W.R, etc. can be specified as bellow.
 

★Frequency: Full badn of white space band
★Bandwidth: 1M to 1GHz
★Attenuation: up to 80dB
★Others: IL, RL, Power, Size, V.S.W.R, etc.

 As above, we enable to cover the various RF & Microwave components, such as Cavity Filter, SMD DR Filter and Helical Filter in Highpass filter, Lowpass fitler and bandpass filter and bandstop Filter (Notch Filter) as well.

Besides, the special place from Temwell group is that, in Temwell website, there are more than 3000 ready-made RF Filter specifications online for development reference, or reference for frequency designation, while providing more than 800 standard products for 72 hour shipping, providing learning kit special program for the purpose of education program. All are great to start your new design project.

Final, let me share one excellent feature of Helical Filter is self-turning function which is good for new prototype with low budget case.
