VCO (Voltage Controlled Oscillator) of Exciter Design For Electronic Jammer Using IC MC 1648
Jamming is a way for disabling electronic communications by cover up a signal from a transmitter with another signal. Jamming signal emitter consists of Frequency monitor, Jammer control, Noise source (Sawtooth generator and or Noise generator), Tx (HF, VHF, or UHF), combiner and HPA (high power amplifier). In this paper, exciter in Jammer is designed using integrated circuit MC 1648 type. Its working frequencies are 30 MHz to 80 MHz. They are divided into 20 bands, each band of 2.5 MHz width. The Exciter design result with VCO for only two band, ie VCO1 with output frequency 30 MHz - 32.5 MHz and VCO2 with output frequency 32.5 MHz - 35 MHz.
