MAAD-011021 Digital Attenuator, 6-Bit, 0.5 dB LSB step Rev. V3 DC - 30 GHz Features 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. 3 Pin Configuration The attenuator integrates an inverter to allow a single control for series/shunt attenuation. Inverter Pin No. Function Pin No. Function requires a -5 V supply (V ) and 17 mA typical, logic CC is 0 V / +5 V. 1 Ground 9 V6 (16 dB) The device is also available as bare die order part 2 RF Input 10 Ground number MAAD-011021-0GPDIE. 3 Ground 11 RF Output 4 V1 (0.5 dB) 12 Ground 5 V2 (1 dB) 13 No Connection 1,2 6 V3 (2 dB) 14 No Connection Ordering Information 7 V4 (4 dB) 15 V -5 V Bias CC Part Number Package 8 V5 (8 dB) 16 No Connection MAAD-011021 Bulk Part 4 17 Pad MAAD-011021-TR0500 500 piece reel 3.
