Pasternack launches series of waveguide packaged, voltage variable attenuators

Pasternack’s waveguide packaged, voltage variable attenuators utilise GaAs MMIC semiconductor technology and offer 0 to 30dB attenuation tuning adjustment with a voltage range of 0 to 5Vdc.

Designers will find these broadband, voltage variable attenuators useful in receive chains to tune mm-wave signal levels to optimise system-level performance.

The attenuators are available in rugged, compact, military-grade, gold-plated aluminium package designs that operate across −10 to +60^oC. 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 features a fast switching speed of 25nsec typical, insertion loss ranges from 4 to 6dB, and high-input power handling up to +23dBm.

“Our new line of high-reliability, waveguide packaged, voltage variable attenuators is ideal for downlink or receive channels where adjusting/tuning signal levels to optimise system-level performance is necessary. These continuously variable waveguide attenuators are in-stock and available to ship the same day ordered," said Tim Galla, Product Manager.

Pasternack’s new waveguide packaged, voltage variable attenuators are in-stock and ready for immediate shipment with no minimum order quantity.
