Radio Frequency Generator (RFG) is a tool used to generate the RF frequency. In the experimental modulation technique Radio Frequency Generator (RFG) is used as a carrier signal generator (carrier). The series of Radio Frequency Generator (RFG) can generate frequencies from 150KHz - 12 MHz. The series of Radio Frequency Generator (RFG) has been equipped generator modulation signal (information signal) that can be used to adjust the position of switch SW2. The series of Radio Frequency Generator (RFG) is also equipped with output level control via potensio VR1 and the output impedance selector selector with SW1. The series of Radio Frequency Generator (RFG) is also equipped with selector selector frequency band consisting of 5 range. For more details can be seen from the picture series of Radio Frequency Generator (RFG) follows.

The simplest is the use of transistors or often called a flip-flop. There also are using integrated circuit such as IC 555. Theres more to exploit the resonance of the capacitor and inductor relationship as oscillators. To be sure whatever form and whatever the circuit components used must be able to generate electric waves which have a peak voltage (logic 1) and valleys (logic 0) is continuous.

Any variation of pulse generator circuit design has advantages and disadvantages of each, just how your decision for the appropriate circuit. For example to create a clock signal for a simple utility that you can only take advantage of the transistor but if you need a more accurate clock signal and form a perfect balance you can use IC Astable or logic gates. Or perhaps you need a signal with very high frequency (up to MHz) you can use a combination of inductor, resistor and capacitor.

Frequency value of the pulse generator circuit gate above is determined by the value kapaitor C2, R2, R3 and VR2. The greater the value of these components will lower the frequency and vice versa. Actually nothing is difficult to make a series of pulse generators, almost all time-based series is utilizing the nature of the charge and discharge capacitor. Therefore, like any form of variations in pulse generator circuit, always have a larger capacitor value will make the frequency produced smaller or longer periods of time, sedangkaan smaller capacitor values ​​will result in greater output frequency.
