Hi,
When I was looking at an IF amp in the "Experimental mathods in RF", I
noticed a filter I have not seen before.
I will try to describe:

200 Ohm i/p impedance feeding 1 cap. The othe side of the cap feeds
another cap down to ground and an inductor. The other side of the inductor
has a cap down to ground. The junction of the ind and cap, has another cap
feeding a load of 100 Ohm.

When I simulate this it is a bandpass filter.

What do you call this filter, and where can I find some info about it?

Thanks,
John
