The AD6624A is part of Analog Devices’ SoftCell® multicarrier transceiver chipset designed for compatibility with Analog Devices’ family of high sample rate IF sampling ADCs (AD6640/ AD6644 12- and 14-bit). The SoftCell receiver comprises a digital receiver capable of digitizing an entire spectrum of carriers and digitally selecting the carrier of interest for tuning and channel selection. This architecture eliminates redundant radios in wireless base station applications. High dynamic range decimation filters offer a wide range of decimation rates. The RAM-based architecture allows easy reconfiguration for multimode applications. The decimating filters remove unwanted signals and noise from the channel of interest. When the channel of interest occupies less bandwidth than the input signal, this rejection of out-of-band noise is called “processing gain.” By using large decimation factors, this “processing gain” can improve the SNR of the ADC by 30 dB or more. In addition, the chipset includes a demodulator, IF filters, and ADC for receiving, demodulating, and digitizing RF signals.
