Regarding Cavity filter used in GSM base station~~~~

[Reinhardt]

Hi all,

I am going to work for a telecommunication manufacturer as product engineer. The interviewer of this company told me that his department is working toward the volume production of filter unit (FU) which could be used in GSM base station.

What I want to know is which kind of filter is being most frequenlty used in base station? Combline Cavity filter? interdigital filter?

Thanks a lot!
