Attenuators

Digital Controlled, 4-16 GHz



Our family of digitally programmable attenuators cover the frequency range of 4-16 GHz. Attenuation ranges of 32 dB and 64 dB are standard, with 8 bits of resolution. LSB of 32 dB models is 0.125 dB, and for 64 dB models LSB is 0.250 dB. Each model includes an internal integrated linearized driver, an internal clock, and a D/A converter. Options of 12 bits resolution are available.
