* 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/AN9820.1 Applications
* such as PCS phones, cordless telephones, wireless card readers, bar code scanners, and other handheld portable appliances. Referring to Figure 2, note that with the exception of the proprietary HFA3860B baseband processor and the medium access controller (MAC) chip, all the RF/IF front end functiona
