FUTURE-PROOF BASE STATIONS WITH NEXT-GENERATION DIGITAL RADIO
The Analog Devices AD6640/AD6620 Multi-Channel Multi-Mode Receiver Chipset provides a breakthrough design for digital radio receivers, enabling programmable wideband radio base stations. The solution utilizes the AD6640, a wideband analog-to-digital converter capable of sampling at 65 MSPS, and the AD6620, a 65 MSPS decimating receiver chip. This advanced 'software' receiver allows the same radio to be tuned to different channels and even different air interface standards.
| AD6640 Sampling Rate | 65 MSPS |
|---|---|
| AD6640 Bandwidth | 25 MHz |
| AD6640 SFDR | 80-100 dB |
| AD6640 SNR | 70 dB |
| AD6640 Supply Voltage | +5 V |
| AD6640 Package | 44-pin TQFP |
| AD6620 Sampling Rate | 65 MSPS |
| AD6620 SFDR | Greater than 100 dB |
| AD6620 Package | 80-pin PQFP |
| AD6620 IF Sampling | 70 MHz |
The chipset supports AMPS, IS136, CDMA, GSM, PCS1900, PHS, PDC, ETACS, and NMT.
It replaces multiple analog radios with a single ADC and uses digital tuner/filter chips instead of analog synthesizers and channel-select filters.
Yes, capacity can be increased by simply adding digital tuner/filter chips to demodulate additional RF channels.
