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.
