The modules display VSWR over all attenuation levels and CW input power is rated up to 23dBm, according to Fairview Microwave.

RF components supplier Fairview Microwave has released a new line of voltage variable attenuators (VVAs) that offer up to 60dB of attenuation across a broad range of frequencies from 400MHz to 18GHz.

The new PIN diode-based VVAs deliver accurate control and broadband flatness, allowing the output level to be continuously adjusted by changing analog voltage on the input control line. These VVAs are ideal for use with variable gain amplifiers, power level control, feed-forward amplifiers and automatic level control (ALC) circuits, according to Fairview.

The product line is comprised of six models that support frequencies from 400MHz to 18GHz while providing low insertion loss and a wide dynamic range. These modules display VSWR over all attenuation levels and CW input power is rated up to 23dBm, according to the company. Rugged coaxial packaged assemblies are designed to meet MIL-STD-202 environmental test conditions that include humidity, shock and vibration.

The VVAs are frequently used in applications such as electronic warfare, instrumentation, point-to-point and point-to-multipoint radios, fibre optic and broadband telecom, microwave radio and VSAT, military radios, radar, ECM, SATCOM and sensors, and R&D, according to the company.

Fairview’s new voltage variable attenuators are in-stock and ready to ship.
