Launch of 3GSPS RF Sampling Analog-to-Digital Converter
Simplifying Direct RF Sampling System Architecture

Texas Instruments (TI) (President and CEO Kent Jeon) announced the introduction of the ADC32RF45, the industry's fastest 14-bit analog-to-digital converter (ADC) that achieves the highest level of RF sampling performance.

This dual-channel ADC enables direct RF signal conversion up to 4 GHz, enabling engineers to take advantage of maximum dynamic range and input bandwidth. The ADC32RF45, the first in a new family of data converters in TI's RF sampling portfolio, is a multiband receiver that simplifies system architecture and reduces board space by up to 75 percent by eliminating up to four intermediate-frequency downconversion stages.

Direct RF sampling meets the needs of engineers seeking higher integration, better noise performance, wider bandwidth, and smaller footprints in radar, software-defined radio (SDR), aerospace and defense, test and measurement, wireless communications, and radio astronomy systems.



This product supports RF input up to 4 GHz, enabling direct conversion of RF signals to the first, second, and third Nyquist zones, reducing filter complexity and saving board space and component count.

Additionally, the ADC32RF45 can detect even very weak signals with an industry-leading spectral noise density of -155 dBFS/Hz, which is 5 dB better than competing products. It also provides the industry's best signal-to-noise ratio of 58.5 dB at a 1.8 GHz input frequency.

As the fastest 14-bit ADC with a maximum sample rate of 3 GSPS, it provides an instantaneous 5 GHz of bandwidth per channel, enabling engineers to design wideband phase and quadrature component receivers exceeding 2.5 GHz.

As a multiband and digital downconverter, it can extract one or two subbands per channel, reducing digital interface data throughput by up to 92% and saving system size, power, and processing resources.

The ADC32RF45EVM is available now from the TI store for $2,499, and the TSW14J56EVM data capture card is available for $1,249. Additional support is available with TI Designs reference designs and application notes.
