AFE7071 (ACTIVE)

Integrated Dual 14-bit 65MSPS DAC and RF IQ Modulator

 

Special Note

The AFE7071 integrates a dual digital-to-analog converter (DAC), tunable baseband filters, IQ modulator and digital quadrature modulation correction circuit. The AFE7070 adds a direct digital synthesizer (DDS) with 32-bit numerically controlled oscillator (NCO) and LVDS output buffer.

Description

The AFE7071 is a dual 14-bit 65-MSPS digital-to-analog converter (DAC) with integrated, programmable fourth-order baseband filter and analog quadrature modulator. The AFE7071 includes additional digital signal-processing features such as a quadrature modulator correction circuit, providing LO and sideband suppression capability. The AFE7071 has an interleaved 14-bit 1.8-V to 3.3-V CMOS input. The AFE7071 provides 20 MHz of RF signal bandwidth with an RF output frequency range of 100 MHz to 2.7 GHz.

The AFE7071 package is a 7-mm × 7mm 48-pin QFN package. The AFE7071 is specified over the full industrial temperature range (–40°C to 85°C).
