Voltage Variable Attenuators from Pasternack Offer Up to 60 dB Attenuation Covering Frequencies from 400 MHz to 18 GHz
Pasternack, a leading provider of RF, microwave and millimeter wave products, introduces an all new line of voltage variable attenuators offering up to 60 dB of attenuation across broad frequencies from 400 MHz to 18 GHz. This line of voltage variable attenuators is most commonly deployed in applications such as electronic warfare, instrumentation, point-to-point and point-to-multipoint radios, fiber optic and broadband telecom, microwave radio and VSAT, military radios, radar, ECM, SATCOM and sensors, and R&D.
In most communications systems, the RF components used (transmitters, receivers, mixers, multipliers, attenuators, amplifiers, VCO’s, phase locked loops, etc.) may require specific power levels to run optimally. These power levels may differ from one component to the next in a system network and may require the attenuation level to be finely adjusted to account for changes in received signal levels or to optimally match the input power into a sensitive circuit. Pasternack’s new PIN diode-based voltage variable attenuators (VVAs) provide accurate control and broadband flatness where the output level can be adjusted continuously by varying an analog voltage on the input control line. These VVA’s are ideally suited for use with variable gain amplifiers, power level control, feed-forward amplifiers, and automatic level control (ALC) circuits.
The new portfolio of voltage variable attenuators from Pasternack includes 6 models covering octave broadband frequencies from 400 MHz to 18 GHz while boasting low insertion loss and wide dynamic range. Moreover, these modules display excellent VSWR over all attenuation levels. CW input power is rated up to +23 dBm. Each unit is designed into rugged coaxial packages to meet MIL-STD-202 environmental conditions.
“A high-rel design like these VVAs normally commands long lead-times from OEMs, however, Pasternack has each model available from stock for immediate shipment,” says Tim Galla, Active RF Components Product Manager at Pasternack.
Pasternack’s new voltage variable attenuators are in-stock and ready to ship today. You can view the new VVAs by visiting http://www.pasternack.com/pages/RF-Microwave-and-Millimeter-Wave-Products/voltage-variable-attenuators.html
