Product Detail

The MAAD-011021 is a wide band 6-bit digital attenuator covering DC to 40 GHz. The attenuation bit-values are 0.5 dB LSB (least significant bit), 1, 2, 4, 8, and 16 dB for a total attenuation of 31.5 dB. Attenuation error is typically less than +/- 0.5 dB, RMS phase error is less than 5 degrees at 20 GHz, and typical insertion loss is 7.1 dB at 15 GHz. Return loss is typically 12 dB across all frequencies and attenuation states. The attenuator integrates an inverter to allow a single control for series/shunt attenuation. Inverter requires a -5 V supply (VCC) and 17 mA typical, logic is 0 V / +5 V. The device is also available in a lead-free 3 mm 16-lead PQFN plastic package; order part number MAAD-011021-TR0500.
