Anadigics_aca2431_PR_PhotoFrequency range makes it suitable for new DOCSIS 3.1 CATV standard

Richardson RFPD Inc. announced the availability and full design support capabilities for a new power doubler amplifier from ANADIGICS.

The ACA2431 is a highly linear, high output power integrated RF amplifier designed for CATV headends and HFC distribution systems. The IC consists of two parallel amplifiers that are optimized for exceptionally low distortion, high output power, and high crash point. A GaN output stage is incorporated to minimize the operating (bias) current, making this device an excellent choice for environmentally friendly, “green” initiatives. The ACA2431 provides high gain over the 50 to 1218 MHz CATV downstream band, and is cascaded between two transmission line baluns.

The ACA2431 is ideally suited as an output power doubler for deep fiber node in CATV distribution and as a CATV digital edge QAM output driver. It is offered in a thermally-enhanced surface mount package.

“Because this amplifier covers up to 1218 MHz, it is suitable for the new DOCSIS 3.1 CATV standard, which will improve CATV performance, speed and bandwidth” commented Dave Silvius, Director, Strategic Marketing, Richardson RFPD. “Combining that with the low bias current for this level of output power that is enabled by the GaN efficiency makes this a very appealing device.”

According to ANADIGICS, additional key features of the ACA2431 include:

  • 50 to 1218 MHz frequency range
  • +59 dBmV output power
  • 28 dB gain @ 1.218 GHz
  • Single +24V supply
  • Operating current = 460 mA
  • High linearity: -78 dBc CTB, -66 dBc CSO, -65 dBc XMOD
  • External current control for lower power applications
  • 10.3 mm x 10.3 mm SOIC-16 package
