Fairview Microwave announced new digitally controlled programmable attenuators targeted to perform the important function of signal processing in a variety of RF, microwave, and millimeter-wave systems. Offering up to 40 GHz frequency range and up to 60 dB attenuation range with 0.03 dB minimum step size, these programmable attenuators are commonly used in electronic warfare, military and space communication systems, radar and test and measurement applications.
The devices can be used in transceiver RF and IF sections and in equipment applications such as signal generators to adjust the output level of test signals. The designs utilize PIN diode semiconductor technology that generates extremely fast switching performance between attenuation states over wide frequency bands.
Programmable attenuator control bit sizes range from 5 to 10 bits. All attenuators are powered and command controlled via 15 pin female Micro-D socket or USB interface.
The attenuators are available in environmentally sealed rugged metal packages with either stainless steel SMA or 2.92mm connectors. Operating temperatures are over -50°C to +85°C.
