Pasternack has introduced a new line of voltage variable attenuators with a 60 dB attenuation range from 400 MHz to 18 GHz. This line of voltage variable attenuators has been developed for 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. These 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. The VVA’s are ideally suited for use with variable gain amplifiers, power level control, feed-forward amplifiers, and automatic level control (ALC) circuits.
Pasternack's new portfolio of voltage variable attenuators includes 6 models covering octave broadband frequencies from 400 MHz to 18 GHz with a low insertion loss and wide dynamic range. These modules cab handle up to 23 dBm of CW power with am excellent VSWR over all attenuation levels. Each unit is designed into rugged coaxial package to meet MIL-STD-202 environmental conditions.
These new voltage variable attenuators are in-stock and ready to ship today.
