Features

Paladin waveshaper achieves significant crest factor reduction while maintaining in-band and out-of-band characteristics that are well within the minimum requirements prescribed by the 3GPP/3GGP2 specifications.

Waveshaper achieves up to 2.5 dB of additional PAR reduction over simple baseband clipping, and up to 4 dB of reduction compared to the uncompensated signal, allowing systems to achieve greater power efficiency. In addition, Waveshaper provides high-precision (floating point) programmable baseband filtering, eliminating the need for a separate device to perform this function.

The PM7819 Waveshaper complements the PM7800 and PM7815 PALADIN devices in three key ways:

  • Controls the crest factor, or peak-to-average ratio (PAR), of a WCDMA or CDMA2000 signal while minimizing spectral regrowth, allowing the power amplifier (PA) to be driven harder yielding improved power efficiency.
  • Reduces the cost and complexity of the transmitter sub-system by eliminating the need for separate transmit pulse-shaping filters and interpolators in the customer's baseband modems.
  • Facilitates the implementation of a PALADIN enabled digital multicarrier BTS design by eliminating the need for a separate multi-carrier combiner FPGA or ASIC in front of a PALADIN 10 or PALADIN 15.
