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
