Analog front-end ICs

6 February 2013 Analogue, Mixed Signal, LSI

Texas Instruments introduced two analog front ends (AFEs) for test and measurement, wireless communications and optical networking equipment. The AFE7071 is a complete radio transmitter that integrates a dual digital-to-analog converter (DAC), tuneable baseband filters, IQ modulator and digital quadrature modulation correction circuit. The AFE7070 adds a direct digital synthesiser with 32-bit numerically controlled oscillator and LVDS output buffer. The devices are tuneable from 100 MHz to 2700 MHz with output power up to 0,3 dBm. Adjacent channel power ratio is 66 dB with 5 MHz WCDMA and 61 dB with 20 MHz LTE at 2,1 GHz while using only 325 mW. A low output noise floor of 156 dBm/Hz enables high signal quality.
