Our line of digitally controlled programmable attenuators perform up to 40 GHz and up to 60 dB attenuation range with 0.03 dB minimum step size. These attenuators perform the important function of adjusting the amplitude of signal levels in RF, microwave, and millimeter-wave systems. The designs utilize PIN diode semiconductor technology that generates extremely fast switching performance between attenuation states over wide frequency bands. This performance is highly desirable and widely used in transceiver RF and IF sections and in equipment applications such as signal generators to adjust the output level of test signals.
Our programmable attenuators have integrated TTL driver logic control bit circuitry that ranges from 5 to 10 binary bits depending on the model. This number of bits benefits in very precise and linear digital control of attenuation step sizes that can be as low as 0.03 dB to 1 dB maximum over the entire attenuation range. The command control interface is via a 15 pin female Micro-D socket or USB connector. The circuits are enclosed in environmentally sealed metal packages with epoxy paint finish with either stainless steel SMA or 2.92mm connectors. Guaranteed operating performance covers a temperature range of -50°C to +85°C.
