VHF UHF Broad Band BPF
Temwell presents RF BP Filter for VHF UHF BroadBand Filter application. Base on over 25years experience and our full series RF engineer team, we are confident to provide complete custom solution of BroadBand Filter during Frequency band from 250MHz to 40GHz with Bandwidth performance from 100MHz to 20GHz .
What is a broadband filter or wideband filter?
A broadband filter (wideband filter) especially means broadband bandpass filter, which is a RF component that allows multiple frequency bands or signals work at the same time. Without broadband filter (wideband filter), you will suffer un-expected frequency interfere or noise when your RF device is operating on specific purpose.
How does a broadband filter work?
The important feature of broadband filter is that it can cover a wide range of bandwidth, and outside of the required bandwidth, it can immediately provide good cut-off performance in Attenuation value, so that RF products can be well protected. In RF circuit, it needs just one RF component can support and assist many applications of different RF communication products to isolate noise. It is an important and common RF component in the use of various RF products.
Temwell as worldwide expert in RF Filter and Microwave design and manufacture supply customized solution of all kinds RF & Microwave Components in RF Transmission circuit , and providing one-stop service for worldwide clients based on our over 25years experience. Give you the quick proposals and adequate solution in all kinds of RF $ Microwave components are always our top mission and main goal.
Temwell can supply the custom service in very wide Bandwidth value and have good cut-off Attenuation value performance at one time. In addition, we can professionally provide customized center frequency parameters, ranging from 250MHz to 40GHz.
Especially, we could provide broadbroad filter with adjustable Center Frequency function, which is useful in your prototype testing to reduce the cost and developing time. As above, we not only provide custom spec service, but also enable to cover the various RF & Microwave components, such as Cavity Filter, SMD DR Filter and Helical Filter as well. For detailed parameters, please refer to the following
★BW: 100~20GHz bandwidth with fixed Fc
★BW: 100~200MHz Bandwidth with adjustable Fc
★RL: 15db up
★Cut-Off ATTENUAITON: 30-50db at least
★type: Cavity Filter, SMD DR Filter and Helical Filter
Here we demo VHF UHF BroadBand B.P. Helical Filter in finished spec sheet and curve with curve performance as following in 3 pole series and 4 pole series. The difference in between is the Attenuation performance. 4 pole series has 10dB better than 3 pole series.
