RF Signal Generator Antenna Impedance

Radiofrequency RF signal generation is a necessary part of the instrumentation for most any field where RF or wireless electromagnetic test is undertaken. Rather than using electrical conductors, many technicians prefer to use antenna-based RF signal generation devices. Unlike many electrical devices, the RF signal jammer does not make any measurements, only gives the correct signal test conditions for other devices to measure the performance of the output. These jamming devices allow the technician to “see” a device’s performance in certain situations, which allows them to identify problems with the device before they become serious enough to require a more thorough inspection. The jammer also allows technicians to make their tests and measurements of RF interference to ensure that the interference will not interfere with other communications.

Signal Jammers and Generators

There are several types of rf signal jammer devices on the market, and they all perform similarly. They all use the same type of measurement, either power or RF bandwidth measurement. Some of these types use both methods, and some use only one or the other. Regardless of the type of signal jammer you use, your main concern is to reduce the modulation distortion caused by radio frequency noise.

This can be accomplished in a variety of ways, ranging from physically eliminating unwanted reflections to ensuring that the RF signal generator is set up to produce the lowest possible rf signal level when the transmission is complete. In most cases, the best solution is to place the rf signal generator far enough away from the receiving circuit to eliminate any possibility of a poor signal being sent. This may be a physical distance from the source of the transmitted signal, or it could be a time span or several periods.


To test equipment that operates using a microwave, the frequency level is changed and the resulting strength is measured. If the result is below the desired level, you should examine the circuit to determine what the problem is. In most cases, this problem is something physical such as a wire getting disconnected at the feed point. It may also be a combination of mechanical issues and RF interference.

The way that the microwave works is based on the principle of a single-sided frequency division. To put it simply, two signals are separated by a layer of frequencies. The two sounds can then be fed into separate channels. Usually, each channel is intended for a particular purpose, such as low-frequency radio broadcast or voice communication over a phone line. However, some antennas use a broader channel, such as for broadcasting higher frequencies.

The way that this system works is based on the law of least power consumption. An antenna will only accept signals when its maximum power is utilized. If an antenna is too weak to receive or send signals at its maximum power, it will not work. Conversely, an antenna that is strong enough to send or receive signals but too weak to use the maximum power will not work either.

Antenna Impedance

The first thing that needs to be adjusted is the antenna impedance. Antenna impedance directly affects the output stage of the amplifier. The output stage consists of a pair of conductors that are wired in series to create a voltage. When the voltage falls below the desired level, the amplifier steps down so that current is not drawn from the batteries.

To adjust the antenna impedance, simply cut the existing wires. This will allow you to reduce the power levels on the transmitter. After the cut, connect new wires where the cut was made. You will then need to reattach the antenna to the transmitter.
