Produktoversigt

The MAX2009ETI+ is a 1200MHz to 2500MHz adjustable RF pre-distorter in 28 pin TQFN package. It is designed to improve power amplifier (PA) adjacent-channel power rejection (ACPR) by introducing gain and phase expansion in a PA chain to compensate for the PA's gain and phase compression. With its +23dBm maximum input power level and wide adjustable range, the MAX2009 can provide up to 12dB of ACPR improvement for power amplifiers operating in the 1200MHz to 2500MHz frequency band. The MAX2009 is unique in that it provides up to 7dB of gain expansion and 24° of phase expansion as the input power is increased. The amount of expansion is configurable through two independent sets of control, one set adjusts the gain expansion breakpoint and slope, while the second set controls the same parameters for phase. The linearization circuit can be run in either a static set and forget mode or a closed-loop implementation can be employed with real-time software controlled distortion correction.
  • Supply voltage range is 4.75V to 5.25V
  • Operating temperature range from -40°C to 85°C
  • Exceptional gain and phase flatness
  • Group delay is less than 1.3ns (gain and phase sections combined)
  • ±0.04ns group delay ripple over a 100MHz band
  • Capable of handling input drives up to +23dBm
  • On-chip temperature variation compensation
  • Low power consumption is 75mW (typ)
  • Hybrid correction modes is possible using simple lookup tables
