![]() ![]() The main characteristic of the antenna is VSWR (Voltage Standing Wave Ratio). The Transmitting Antenna is the device that transmits the signals generated by your jammer. However, it should be borne in mind that the greater the power, the shorter the device’s operating time. More power equals less battery life.Ī fairly wide selection of amplifying stages on the market for electronic components (7dBm, 17dBm, and even 20+dBm). The price of this is, as you probably guessed, the device’s operating time. The more power your signal jammer has, the wider the radius of its suppression. The RF Amplifier is what you need if you want to expand the coverage of your jammer along with the signal strength. It is programmed once and connected to the VCO, so it is not configurable. For this purpose, you need to use a microcontroller. The closed loop circuit uses a PLL to adjust and hold the frequency of the VCO at the same level. The sawtooth generator causes the VCO to go from low to high frequency. The open circuit is simple and requires only a few additional passive components. The tuning circuit can be of two types: open circuit and feedback. You also need to think about the size of the future jammer as you can create
