Fairview Microwave’s new line of voltage variable attenuators (VVA) offer up to 60 dB of attenuation across a broad range of frequencies from 400 MHz to 18 GHz. The VVA product line is comprised of six models that provide low insertion loss and wide dynamic range, as well as exceptional VSWR over all attenuation levels. CW input power is rated up to +23 dBm. Fairview’s PIN diode-based VVAs deliver accurate control and broadband flatness, allowing the output level to be continuously adjusted by changing the analog voltage on the input control line.
RF components used in most communications systems require precise power levels to achieve peak performance, and these power requirements can vary from one component to the next. This results in the need to fine-tune the attenuation to make up for fluctuations in received signal levels or best match the input power to a sensitive circuit. For these situations, a VVA is required to ensure optimal performance. Fairview Microwave’s VVAs are ideal for use with variable gain amplifiers (VGA), feed-forward amplifiers, power level control and automatic level control (ALC) circuits.
The rugged coaxial packaged assemblies are designed to meet MIL-STD-202 environmental test conditions, including humidity, shock and vibration. Package interface options include SMA female connector to 15 PIN D-sub female, 15 PIN Micro-D female or RFI pins. For added flexibility, the SMA connectors are field replaceable. Each model is powered by +12 V DC.
Fairview Microwave’s VVAs were designed for electronic warfare, instrumentation, point-to-point and point-to-multipoint radios, broadband telecom, fiber optic, VSAT, SATCOM, military radios, radar, sensors and R&D applications.
