Analog Devices AD6600/AD6620 Diversity Receiver Chipset Product Description
Analog Devices presents a highly integrated Diversity Receiver chipset comprising the AD6600 dual-channel IF sampling ADC and the AD6620 dual-channel decimating receiver chip. This solution is designed to reduce the size and cost of base station receivers by replacing sensitive analog filters with on-chip digital filtering.
The chipset supports various air interface standards, including GSM, CDMA, S136, and PHS. Key features include a high dynamic range of 80 to 100+ dB, automatic gain control, and compatibility with general-purpose DSPs. The AD6600 provides an 11-bit 20 MSPS ADC, while the AD6620 offers a spurious free dynamic range greater than 100 dB.
