Standard BPF for Ham Radio User

 
 
     

Temwell RF BandPass Helical Filter released standard series for open frequency  area users, such as, Ham radio, Amateur radio, Free User, etc. Referring to national regulation of United States,  Temwell support 6 standard frequency spec, Fo=146MHz, 232.5MHz, 435MHz, 915MHz, 1270MHz,1282.5MHz, in many different kind of size and  applications, EX: Pin type and Module type with different connector type.

 We are also desired to build new standard series for Ham radio user in 
European area, Australia area, South Africa area, South America area, etc.  Welcome to contact us for more detail discussion.
