I am trying to design a bandpass filter with LTC1562-2 IC.
I have to have approximately 20dB gain, narrow bandwidth (5k~10kHz).
I tried to test a design with filter CAD from linear devices website.
The center frequency I have to use is 245kHz.
My results were not very satisfying.
I could only get around 30kHz bandwidth.
my alternate solution for this is designing LC filter with PSpice.
I have attached the circuit and the waveform that I got (Fc=245kHz).
again, main goal is to get 20dB gain and narrow bandwidth of 5k~10kHz if possible.
