Square signal generator 100 kHz – 5 MHz

The generator is based on LT6900 integrated circuit. In this situation, it is possible to build it easily and place it in small enclosure. Amplitude and frequency regulation is carried out on potentiometers. With the help of the switches, you can select the frequency control range and the power mode.

The device can be powered from a 9 V battery or a USB connector. Thanks to the low noise RT9193 stabilizer it is possible to obtain a stable voltage of 3.3 V. The operating range 100 kHz – 5 MHz was determined based on the prototype – in these ranges the shape of the signal was closest to the rectangular one. Nevertheless, the IC can work up to a frequency of 20 MHz.
