I am attempting to implement a monolithic crystal filter (ECS-96SMF) into a
50 ohm IF. It will sit between a 50 ohm active mixer and a 50 gain block. I
was really surprised that the manufacture doesn't tell you how match it into
a 50 ohm system or have any app notes. It says the insertion loss should be
around 3 dB but is that relative to a 50 ohm system? and what matching
components do you use? If this were a saw filter I would have the matching
components values and even typical layout of the circuit. All I get from the
crystal filter manufactures is a one page datasheet with no matching info.
Any thoughts on the matter?
