Direct RF-sampling ADCs

9 November 2011 Analogue, Mixed Signal, LSI

National Semiconductor introduced a family of analog-to-digital converters (ADCs) said to be the industry’s first to directly sample RF signals beyond 2,7 GHz, with third-order intermodulation distortion (IMD3) up to -71 dBc and sampling at up to 3,6 Giga-samples per second (GSps).

The ADC12Dxx00RF family includes five 12-bit ADCs that enable system designers to eliminate multiple intermediate frequency (IF) down-conversion stages including amplifiers, mixers and filters. A single chip can replace entire radio signal path subsystems in 3G/4G wireless base stations as well as microwave backhaul, military and wideband software-defined radio (SDR) applications.

The ADC12D1800RF provides interleaved single-channel sampling rates up to 3,6 GSps or dual-channel rates up to 1,8 GSps, with IMD3 of -64 dBc at 2,7 GHz. The ADC12D1600RF provides interleaved single-channel sampling rates up to 3,2 GSps or dual-channel rates up to 1,6 GSps, with IMD3 of -70 dBc at 2,7 GHz. The ADC12D1000RF provides interleaved single-channel sampling rates up to 2,0 GSps or dual-channel rates up to 1,0 GSps, with IMD3 of -69 dBc at 2,7 GHz.

The ADC12D800RF provides interleaved single-channel sampling rates up to 1,6 GSps or dual-channel rates up to 800 MSps, with IMD3 of -71 dBc at 2,7 GHz. The ADC12D500RF provides interleaved single-channel sampling rates up to 1,0 GSps or dual-channel rates up to 500 MSps, with IMD3 of -69 dBc at 2,7 GHz.
