Waveguide-Packaged, Voltage-Variable Attenuators Cover Wide Frequency Range

Nov. 3, 2022
These attenuators handle mmWave frequency bands from 26.5 to 110 GHz, serving to tune downlink channels to optimize system performance.

The Overview

Pasternack, an Infinite Electronics brand, now provides six new models of waveguide-packaged, voltage-variable attenuators covering popular mmWave frequency bands ranging from 26.5 to 110 GHz.

Who Needs It & Why?

These high-reliability attenuators are suited for downlink or receive channels that require adjusting/tuning of mmWave signal levels to optimize system-level performance.

Under the Hood

The voltage-variable attenuators, which leverage gallium-arsenide monolithic-microwave IC (GaAs MMIC) semiconductor technology, offer 0- to 30-dB attenuation tuning adjustment with a voltage range of 0 to 5 V dc.

The attenuators come in rugged, compact, military-grade, gold-plated aluminum packages that operate across −10 to +60°C and support a UG-383/U-M waveguide flange pattern at the RF input and output ports. Solder pins are used for dc voltage control and ground connections. They support a variety of waveguide sizes and can withstand exposure up to 95% relative humidity and altitudes of up to 10,000 feet.

This portfolio of broadband, waveguide, voltage-variable attenuators feature a fast switching speed of 25 ns typical; insertion loss ranges from 4 to 6 dB; and high-input power handling ranges up to +23 dBm.
