Product Summary
The AD831APZ is a low distortion, wide dynamic range, monolithic mixer for use in such applications as RF to IF down conversion 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 AD831APZ includes an LO driver and a low-noise output amplifier and provides both user-programmable power consumption and 3rd-order intercept point. The AD831APZ provides a +24 dBm third-order intercept point for –10 dBm LO power, thus improving system performance and reducing system cost compared to passive mixers, by eliminating the need for a high power LO driver and its attendant shielding and isolation problems. The applications of the AD831APZ include (1)High performance RF/IF mixer; (2)Direct to baseband conversion; (3)Image-reject mixers; (4)I/Q modulators and demodulators.
