Texas Instruments Introduces AFE7070 and AFE7071 Analog Front Ends

Texas Instruments AFE7070 analog front end (AFE)

Texas Instruments announced the AFE7070 and AFE7071 analog front ends. The two TI AFEs provide low power, high performance and space savings for test and measurement, wireless communications and optical networking equipment. The AFE7070 and AFE7071 are both available now in a 7mm by 7mm QFN package. Suggested retail pricing in 1,000-unit quantities is $11.90 for the AFE7071 and $23.75 for the AFE7070.

The AFE7071 analog front end is a complete radio transmitter that reduces board space by up to 80% compared to discrete implementations. The IC features a dual digital-to-analog converter (DAC), tunable baseband filters, IQ modulator and digital quadrature modulation correction circuit. The AFE7070 analog front end also includes a direct digital synthesizer (DDS) with 32-bit numerically controlled oscillator (NCO) and LVDS output buffer.
