DESCRIPTION
The ZXF36L01 is a versatile analog high Q bandpass
filter. The device contains two sections:
The basic filter section requires 2 resistors and 2
capacitors to set the centre frequency.
operates up to a frequency of 150kHz.
resistors control filter Q Factor. The Q can be varied up
to 50.
The mixer is included to extend the frequency range up
to 700kHz and to permit the centre frequency to be
tuned.
making microprocessor control convenient.
