Pasternack, an Infinite Electronics brand and a leading provider of RF, microwave and mmWave products, now provides six new models of waveguide packaged, voltage variable attenuators covering popular mmWave frequency bands ranging from 26.5 to 110 GHz.

Pasternack’s new waveguide packaged, voltage variable attenuators utilize GaAs MMIC semiconductor technology and offer 0 dB to 30 dB attenuation tuning adjustment with a voltage range of 0 Vdc to 5 Vdc. Designers will find these broadband, voltage variable attenuators useful in receive chains to tune mmWave signal levels to optimize system-level performance.

The attenuators are available in rugged, compact, military-grade, gold-plated aluminum package designs that operate across −10°C to +60°C. They support a variety of waveguide sizes and can withstand exposure up to 95 percent relative humidity and altitudes of up to 10,000 feet.

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

“Our new line of high reliability, waveguide packaged, voltage variable attenuators is ideal for downlink or receive channels where adjusting/tuning signal levels to optimize 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.
