broadband schematic diagram

Be more specific: What is the upper amd lower frequency limits? Gain? Noise Figure? 3rd order OIP?

maybe you can download the book about <microwave broadband amplifier>

Any specification also can...just for practice...thanks

maybe you can find something on this web

If you are going to use a lowpass/highpass series combination of filters, you might want to isolate the two by putting and amplifier stage between them (assuming system operation allows such a thing). Will be much more producible.
