AN9820.1 - A Condensed Review of Spread Spectrum Techniques for ISM Band Systems

Download the AN9820.1 datasheet PDF. This datasheet also covers the AN9820-1 variant, as both devices belong to the same a condensed review of spread spectrum techniques for ism band systems family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • programmable data rate capability with high rates of 11, 5.5 and 4Mbit/s and IEEE Standard 802.11 fallback rates of 2 and 1Mbit/s. By definition the 1Mbit/s and 2Mbit/s data rates utilize DPSK modulation. The 4Mbit/s data rate mode also utilizes DPSK modulation at double the clock rate of the 2Mbit/s mode. For the higher data rates of 5.5Mbit/s and 11Mbit/s, the radio of Figure 2 utilizes MBOK modulation. MBOK modulation will be discussed following a review of some general topics in spread spect.
