Attenuators

Attenuators are network components employed for the purpose of attenuating an electrical signal. This helps limit signal amplitude and minimise signal distortion. The 4302-52 offers a 50-ohm, manually operated attenuator from 100 kHz to 500 MHz. It also provides reliable and repeatable attenuation for digital and analog signals, and its small size makes it an effective solution for both waveguide and coaxial installation.

Application Field

The 4302-52 attenuator is well suited for numerous applications, such as testing of radio transmitters, diode measurements, electronic instrumentation and design verification, impedance matching of components and power meter calibrations. Additionally, it can be used to adjust the output power of a transmitter or aid in fine-tuning the transmission line.

Working Principle

The 4302-52 attenuator operates with a mechanical knob that is secured to a shaft that goes through the housing. As the operator turns the knob, a precision shaft rotates and causes an increase or decrease in impedance of the shaft path. This, in turn, causes a decrease or increase in the energy of the signal passing through the attenuator. The total attenuation is amplified 30 dB.

The attenuator is designed for 50 ohms impedance with an insertion loss of 0.25 dB and enables minimising of signal distortion and preventing signal overload. Its low-interaction design and durability makes the 4302-52 a reliable choice for RF test applications.

The attenuator employs an efficient grounding system that enables shielding from environmental influences, and allows for trouble-free operation and repeatable results. Its rugged, pressure-cast aluminium housing is designed to withstand harsh environments and repeated use. Additionally, the 4302-52 provides superior performance without degrading due to nearby electrical field or corrosive vapours.
