Gigahertz bandwidth based on 28-nanometer CMOS technology

Analog Devices (ADI) announced a new 28-nanometer (nm) DAC, a new addition to its high-speed DAC product line.

The AD9172 meets the requirements of gigahertz-band applications while providing enhanced spectral efficiency suitable for 4G/5G multi-band wireless base stations and 2GHz E-band microwave point-to-point backhaul platforms.

The design is also suitable for production measurement applications targeting multi-mode direct-to-RF signal synthesis. The AD9172 also provides a solution for defense electronics applications requiring a wider detection range.

Built on 28-nanometer CMOS technology, the AD9172 sets a new performance benchmark by delivering best-in-class dynamic range, signal bandwidth, and exceptionally low power consumption. The AD9172, along with the entire new ADC family, will be introduced at the upcoming International Microwave Symposium.

The dual 16-bit, 12GSPS AD9172 achieves direct RF synthesis performance up to 6GHz, eliminating the need for IF-to-RF up-conversion and LO (Local Oscillator) generation, simplifying the overall RF signal chain and reducing system cost.
