Attenuators

PXV1220S-3DBN3-T02 is a type of attennuator, a component that reduces the level of an electric signal without changing its waveform. It is often used in radiofrequency (RF) and microwave applications, such as frequency division multiplexing (FDM) systems, cable TV systems, and cell phone systems. Attenuators are used to reduce the level of a signal to match the output level of devices, like mixers and amplifiers, to prevent damage or noise when connecting two devices.

Application Field

PXV1220S-3DBN3-T02 attenuator is designed to provide consistent attenuation of very high radio frequency signals. It is ideal for RF and microwave application, such as army communication systems, cable TV systems, laboratory instrumentation, communication infrastructure, high speed data transfer links, radar, and satellite systems. It is especially useful for controlling level in systems with multiple amplifiers and multiple antenna systems.

It is also designed to reduce the signal level for antenna systems that receive large signals from long distances. In these cases, the attenuator is used to reduce the signal’s power to a level that is safe for the receiver. It also allows for interoperability between systems that have different power levels.

Moreover, PXV1220S-3DBN3-T02 is also used for testing and calibration of communication systems, antennas, and other radio and microwave equipment. It is capable of providing precise attenuation that is necessary for these types of tests.

Working Principle

The PXV1220S-3DBN3-T02 attenuator works by introducing a resistance into the signal path. The signal is then forced to travel through the resistor, which reduces its strength. The amount of reduction is determined by the resistance value and the electrical characteristics of the signal.

The attenuator is designed to have a stable resistance as temperature changes, which means that it will maintain its attenuation accuracy even when exposed to extreme temperatures or vibration. It is also designed to have a high power rating so that it can safely handle high power signals.

Finally, the attenuator can be adjusted to provide different levels of attenuation depending on the application. This is done by replacing the resistor with one of different resistance values.
