MACOM_MAAM-011186_PR_PhotoDifferential CATV variable gain amplifier operates from 5 to 300 MHz

Richardson RFPD Inc. announced the availability and full design support capabilities for a 75 Ω reverse path variable gain amplifier from M/A-COM Technology Solutions.

The MAAM-011186 is an integrated two-stage differential amplifier operating from 5 to 300 MHz, with an embedded digital step attenuator (DSA) for CATV reverse path applications. It delivers 36 dB modulation error ratio (MER) performance for 64 QAM modulation and is loaded with 39 channels at 52 dBmV per channel. It is optimized for high output power and low current from 8V bias but can also be operated from 5V bias with flexibility to adjust DC current with external components.

The new VGA is offered in a lead-free 7 mm 48-lead PQFN package, making it an ideal solution for high density cards and compact system amplifiers.

According to MACOM, additional key features of the MAAM-011186 include:

  • 39 dB gain
  • 31.5 dB, 0.5 dB steps, 6-bit DSA
  • 3 dB noise figure
  • Serial or parallel attenuator control
  • Differential input and output
  • Low harmonics
  • Power down mode
