AD831 Datasheet Low Distortion Mixer

Manufacturer: Analog Devices

Overview: Low Distortion Mixer AD831.

General 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.

The AD831 provides a +24 dBm third order intercept point for –10 dBm LO power, thus improving system performance and reducing system cost pared to passive mixers, by eliminating the need for a high power LO driver and its attendant shielding and isolation problems.

Key Features
