Fairview Microwave has introduced a new line of Voltage Variable Attenuators (VVAs) that operate from 400 MHz to 6 GHz with a 60 dB attenuation range. RF components used in most communications systems today, require power levels to be precise in order to achieve peak performance. To achieve this the attenuation needs to be fine-tuned in order to make-up for fluctuations in received signal levels or to best match the input power into a sensitive circuit. These 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. They are ideal for use with variable gain amplifiers, power level control, feed-forward amplifiers and automatic level control (ALC) circuits.
The product line comprises of six models that support frequencies from 400 MHz to 18 GHz while providing a low insertion loss and a wide dynamic range. The modules display exceptional VSWR over all attenuation levels and CW input power is rated up to +23 dBm. Rugged coaxial packaged assemblies are designed to meet MIL-STD-202 environmental test conditions that include Humidity, Shock, and Vibration.
The new voltage variable attenuators are in-stock and ready to ship from Fairview. Click here for more information.
