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.
