Description

The ZXF36L01 is a versatile analog high Q bandpass filter. The device contains two sections:
1 Variable Q bandpass filter.
2 Mixer block.

The basic filter section requires 2 resistors and 2 capacitors to set the centre frequency. The filter operates up to a frequency of 150kHz. Two external 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. The local oscillator can be any waveform, making microprocessor control convenient.
