The AD831 is a low distortion, wide dynamic range, single chip mixer, suitable for HF and VHF Receiver RF-IF frequency, second mixer in DMR base station, DC-baseband conversion, quadrature modulation and demodulation, and ultrasound imaging, frequency move detection and other applications.
The AD831 has provide +24 dBm third-order intermodulation intercept point, realization of -10 dBm LO power, without the need for a high power LO drive.
There is no corresponding shielding and isolation problems, therefore, compared with the passive mixer to improve the performance of the system, reduce the system cost.
The mixer is designed as a single power supply, RF, IF and LO ports with DC isolation capacitor, easy to use.
The amplifier has low DC offset characteristics, so it can be used in DC-baseband frequency conversion and quadrature amplitude demodulation.
