TI Launches AFE7444·AFE7422 Transceivers
Both products are equipped with 4 ADCs and 4 DACs.


Texas Instruments (TI) announced on the 14th that it has released two RF sampling transceivers.

The quad-channel 'AFE7444' and dual-channel 'AFE7422' transceivers integrate four ADCs (Analog-to-Digital Converters) and four DACs (Digital-to-Analog Converters) into a single chip.

Engineers can implement multi-antenna direct RF sampling for radar, software-based wireless communication, 5G communication, etc. through two transceivers.

The AFE7444 and AFE7422 provide the highest instantaneous bandwidth (IBW) among RF sampling transceivers and enable processing of up to 600% of data.

Sampling is performed at a maximum of 9GS/s per DAC and a maximum of 3GS/s per ADC. The AFE7444 has four antennas, each transmitting and receiving up to 800 MHz, and the AFE7422 has two antennas, each transmitting and receiving at 1.2 GHz. Engineers can freely design applications from 10 MHz to 6 GHz.

With the AFE7444 and AFE7422, a single device can support up to 8 antennas and 16 RF bands. Additionally, the input frequency can be sampled directly into the C band without an additional frequency conversion step, allowing local oscillators, mixers, amplifiers, filters, etc., to be excluded from the design.

The two transceivers offer greater programmability in their architecture compared to existing RF solutions and can optimize data bandwidth through options such as interference-free bandwidth decimation.

The AFE7444 and AFE7422, which incorporate four ADCs and four DACs into a single chip, reduce the design cycles associated with the manufacturing and testing steps required when designing with individual components, and save 75% of board space compared to using individual RF sampling data converters with a size of 17×17mm.

Engineers can utilize the integration and compact features of the AFE7444 and AFE7422 to optimize the distance to the antenna, enabling the formation of a digital beam in high-frequency and high-density antenna arrays.

The AFE7444 and AFE7422 are available for immediate purchase at the TI Store and official distributors, with prices starting at $1,749.90 and $1,249.90, respectively, for 100 units. The AFE7444EVM and AFE7422EVM evaluation modules, which can evaluate both transceivers, are priced at $2,499 and $1,999, respectively.
