  • Voltage Variable Attenuator

    Pasternack Enterprises, Inc.

    Voltage variable attenuator series offers up to 60 dB of attenuation across broad frequencies. The frequency range of the voltage variable attenuator components is 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. These 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 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.Like the other over 40,000 RF, microwave and millimeter wave components from Pasternack, this voltage variable attenuator VVA series is in-stock. Not only are these VVA components in stock, they will ship the same day as ordered.
