Customized RF Components and Microwave


Temwell as worldwide expert in designing and manufacturing RF Bandpass Filter, especially in RF Helical Bandpass Filter, enable to provide your 6 kinds of different Custom Service as rapid proposal and quick solution within just 14 workdays. Our service is including  " Center Frequency Change", " Bandwidth Change", " Attenuation value adding", " Impendence Change", "Size Change", and " Modulizng" as well. See detail description as following.

(1) Center Frequency Change Service
During 45MHz to 2600MHz (2.6GHz), any one point of frequency band is able to set up for you as your own specific bandpass filter. In the case of other parameters unchanged, you can make customized settings for the center frequency, whether it is ultra low frequency band (under 100MHz) or ultra high frequency band (up to 2GHz), can be designed. Fast design, development can be completed within 14 working days, and physical samples can be tested at the same time.

(2) Bandwidth Change Service
We provide Bandwidth change from 2MHz, 5MHz, 10MHz, 15MHz, 20MHz, 25MHz, 30MHz, 35MHz, 40MHz, 45MHz, 50MHz, 55MHz, 60MHz, 65MHz, 70MHz, 75MHz, 80MHz, 85MHz, 90MHz, 95MHz, 100MHz, 105MHz, 110MHz, 120MHz, and any other Bandwidth you want. Let me know, we will give what you want. Surely, lead time only takes 14 days.

(3) Attenuation Value Adding Service
Temwell bandpass filter has flexible feature by adding pole to upgrade the electronic performance. Based on the 2pole spec value, we could enhance Attenuation value by grading into 3pole, 4pole, 5pole and 6 pole and all other spec parameters are still under the same, such as , Center Frequency and Bandwidth. But the Attenuation value could be increased 10dBc each upgrading. No doubt, lead time only takes 14 days.

(4) Impedance Change Service
Want to modify Impedance value into 75ohm filter without changing any filter parameters for your specific device? Come to review our custom filter service in Impedance. You could simply search anyone from our filter catalog list online and let me know. Temwell design team will make the Impedance change right away. All 50ohm filters are able to be switched into 75ohm filter under exactly the same filter performance, including Center Frequency, Bandwidth, Attenuation, IL, RL, Dimension, etc. Let me supply your own custom 75ohm Bandpass filter. Lead time only takes 14 days still.


(5) Size Change Service
Looking for smaller filter, but still request flexible filter spec support? Temwell bandpass filter will be your great choice,  which enable to make the custom size service to switch into small size with no change in spec value. Contact for more detail discussion. Surely, Lead time only takes 14 days as well.

(6) Modulizing Service
All our over 5000 kinds of Helical bandpass filters with different spec parameters are able to be modulized into connector type with three kinds of different connectors, N (50ohm), SMA (50ohm) and F (75ohm). You don't have to worry about how to install Pin type filter into PCB circuit. Temwell technical team will do it for you. Just select your desired filter and request the connector type for all. Lead time 14 days will complete all your need.
