ALLEN, Texas – Fairview Microwave Inc. in Allen, Texas, is introducing a line of voltage variable attenuators (VVAs) that offer as much as 60 dB of attenuation across a broad range of frequencies from 400 MHz to 18 GHz for applications such as electronic warfare (EW), instruments, point-to-point and point-to-multipoint radios, fiber optic and broadband telecom, microwave radio and VSAT, military radios, radar, ECM, SATCOM, sensors, and research.

RF components used in most communications systems require power levels to be precise to achieve peak performance and these power requirements can vary from one component to the next. This can result in the attenuation needing to be fine-tuned to make-up for fluctuations in received signal levels or to best match the input power into a sensitive circuit.

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

This product line comprises six models that support frequencies from 400 MHz to 18 GHz while providing low insertion loss and a wide dynamic range. These modules have CW input power is rated as much as +23 dBm. Rugged coaxial packaged assemblies are designed to meet MIL-STD-202 environmental test conditions that include humidity, shock, and vibration.
