V2 Features  40 dB Gain  15.5 dB, 0.5 dB steps, 5 Bit Digital Step Attenuator  36 dB MER, 64 QAM 39 Channels, 52 dBmV/ch.  8 V Operation  2.6 dB Noise Figure  Serial or Parallel Attenuator Control  Differential Input and Output  Low Harmonics  Power Down Mode  Lead-Free 7 mm 48-lead PQFN Package  Halogen-Free “Green” Mold Compound  RoHS* Compliant Description The MAAM-011168 is an integrated 2 stage differential amplifier with embedded digital step attenuator (DSA) assembled in a lead-free 7 mm 48-lead PQFN package. The module provides excellent linearity and high output power with greater than 30 dB MER for 64 QAM modulation with 39 channels and 52 dBmV per channel. Gain in the minimum attenuation state is typically 40 dB. The internal DSA offers 15.5 dB attenuation range with 0.5 dB steps. The device is optimized for high output power with 8 V bias and can also operate from 5 V bias if lower DC power consumption and output level is desired. The module also provides a power down function for each of the amplifier stages. This amplifier is ideally suited for use in CATV reverse path applications.

All pins not listed in the table are “No Connection” and should be left unconnected. 4. The exposed pad centered on the package bottom must be connected to RF and DC ground. 5. MACOM recommends grounding pin 40. It is connected to the CMOS controller but does not affect attenuator setting. M/A-COM Technology Solutions Inc.
