RF signal generator circuit with 2N5458
RF signal generator circuit
The signal generator has about a TV tuner has been developed, bringing the local oscillator signal.
The operation of the tuner is left as it was conceived and has continued as an RF converter function.
external circuit was the object of the sweep, a sine wave modulation FM 1Khz standard deviation recorded in addition to the normal CW. An amplifier MMIC recorded among the local oscillator and output was up to 5V output signal. The 10 turn pot permit regular consultations on each of the three intervals with a total of 100-1000MHz.
In use, the generator can be used in different functions: signal generator, frequency converter, a sweep generator and spectrum analyzer.
Display for user control
Here is a varied circuit of the RF signal generator, which are of interest to radio enthusiasts and professionals alike.Transistors T1 and T2, an astable multivibrator oscillating sound in the frequency range 1-2 kHz can be.
RF oscillator is built around . Here a 455kHz ceramic filter / resonator is obtained stable RF.
