An attenuator is an electrical device used to reduce signal power or voltage without significantly altering the wave shape of the signal. The M3933/30-35N is a low-loss DC-to-3-GHz, metal-film, broadband, line-matching, and amplifier-output attenuator that works on the principle of degree of resistance in resistance lattice networks. It is comprised of a series of resistor networks configured in a specific frequency-dependent manner.

The M3933/30-35N is designed to reduce the amplitude of an RF signal by a known amount. It can operate in both fixed and variable settings, depending on the application. In a fixed-attenuator setting, the signal is attenuated in a predetermined, desired amount; in a variable-attenuator setting, the amount of attenuation is adjusted over a wide range. The device is able to reduce signal power or voltage from 0 to 20 dB.

These attenuators are suitable for a wide range of applications. They can be used to match different electrical impedances in RF and microwave systems, such as within amplifiers and transceivers. They can also be used for EMI-RF and radio-frequency interference (RFI) reduction, for impedance matching in antenna or RF circuitry, and for any other device or system that requires an attenuated signal source.

The M3933/30-35N is based on a resistor lattice network. Its core consists of two opposing arrays of resistive elements that are impedance-matched to provide an increase in resistance at higher frequencies. These resistor arrays are connected in a specific manner to create a predetermined resistance profile that is suitable for a given frequency range. This design also helps in the flattening of the network’s resistance as frequency increases, making it ideal for applications that require a controlled level of attenuation over a wide frequency range.

The M3933/30-35N is designed to operate on a DC input power of 21 dBm. The unit is highly efficient in its operation, achieving an insertion loss of only 0.2 dB up to 3 GHz. The network also features excellent return loss of better than 20 dB up to 3 GHz, making it an ideal choice for a broad range of RF applications.

The M3933/30-35N is both robust and reliable. It utilizes a specifically designed, highly stable, low-loss metal-film material that remains stable over a wide range of temperatures. This material also features an excellent thermal-mechanical performance, making it suited for applications that require high-performance devices in harsh environments.

In conclusion, the M3933/30-35N is an excellent attenuator for a broad range of applications, from matching different electrical impedances in RF and microwave systems to EMI-RF and radio-frequency interference (RFI) reduction. It is based on a resistor lattice network design, and features an insertion loss of only 0.2 dB up to 3 GHz and a return loss of better than 20 dB up to 3 GHz. The network is highly efficient and stable, making it reliable in a wide range of operating conditions.
