hello,

I want to design a IF receiver board, the RF input  from 400Mhz to 900Mhz, 40Mhz bandwidth,tuneable,   i want to get 144Mhz IF signal,

I select following chips

ADL5801         downconvertor mixter

ADF4350         LO

AD8375           IF amp

who can tell me how to design the impedance match between ADL5801 and the IF filter, and between IF filter and AD8375 amplifier?

anyone can give me the filter component value ? with schmatic is better.  i want to get enough stopband attenuation(>= 40db)

and passband flatness(<= 0.5db)
