In the figure is the 1GHz preset frequency splitter. The splitter is powered by a +15v single power supply, whose sensitivity is 30mVrms, and it has a dynamic range of 40dB, its working frequency is 100～1000MHz. In the figure, the input signal is coupled to the diode bridge amplitude limiter by the capacitor, the peak value of the limiter output signal is 100mV, which is amplified by the wide frequency calculating amplifier A1, and then coupled to the 4 point frequency circuit by C3. R6 is the output terminal loading of A1, R7 is the input bias resistor of R7. The output is coupled to the 5-point frequency by the capacitor.
