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).
