MAAD-011021 Digital Attenuator, 6-Bit, 0.5 dB LSB step DC - 30 GHz Features        Rev. V3 Functional Schematic 6-bit, 0.5 dB LSB, 31.5 dB range DC to 30 GHz operation Integrated TTL 0/+5V control +/- 0.5 dB typical bit error Low RMS phase 4.3° @ 20 GHz Lead-Free 3 mm 16-lead PQFN package ESD protection for all controls and bias Description The MAAD-011021 is a wide band 6-bit digital attenuator covering DC to 30 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 7.2 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.

V3 Lead-Free 3 mm 16-Lead PQFN† † Reference Application Note S2083 for lead-free solder reflow recommendations. Meets JEDEC moisture sensitivity level 1 requirements. Plating is 100% matte tin over copper. Application Information The MAAD-011021 is designed for extremely wide band and robust attenuation applications. It uses a combination of series and shunt cold channel, multiple-gate FETs to achieve high linearity and accurate attenuation repeatability. We recommend using double bonds at both RF input and output, as well as keeping bondwires as short as possible. This part is the most accurate for X-band applications. The MAAD-011021 has a built in inverter function which allows a single +5 V / 0 V single control for each bit. This is useful if you require very fast switching times and have +5 V / 0 V available. The MAAD-011021 is DC-coupled at both RFIN and RFOUT. If operation at DC is desired, 0 Ω jumpers (or continuous 50 Ω RF lines) should be used in series with RF IN and RFOUT. Customer should take extra care to ensure that the voltage at both RFIN and RFOUT are 0 V; excess voltage can damage the part. If operation at DC is not required, simply use series blocking capacitors. 8 M/A-COM Technology Solutions Inc.
