PRODUCT DESCRIPTION
The AD831 is a low distortion, wide dynamic range, monolithic mixer
for use in such applications as RF to IF downconversion in HF and
VHF receivers, the second mixer in DMR base stations,
direct-to-baseband conversion, quadrature modulation and
demodulation, and doppler shift detection in ultrasound imaging
applications. The mixer includes an LO driver and a low noise
output amplifier and provides both user-programmable power
consumption and third order intercept point.
