Feature

 AD831 is a low distortion, wide dynamic range, single-chip mixers, such as the frequency for lower HF and VHF receiver RF-IF, DMR base station in a second mixer, DC - baseband conversion, quadrature modulation and demodulation, and ultrasound imaging of the Doppler shift detection applications.

Product Features

    AD831 provides +24 dBm third-order intercept point, -10 dBm LO power consumption can be achieved without high power LO drive, there was no corresponding mask and isolate problems, as compared with the passive mixer can be improved system performance and reduce system cost.

    The mixer designed for single power supply, RF, IF, and LO port has a DC blocking capacitors, easy to use. RF and LO input operating frequency up to 500MHz. IF output is single-ended voltage output. With a 250 MHz output bandwidth. A single resistor connected between OUT and FB pin is used to set the gain. The amplifier has a low dc offset feature, which can be used in DC - baseband conversion and quadrature amplitude demodulation DC-coupled applications.

   When the mixer output amplifier and optimum source impedance, the mixer's SSB noise figure at 70 MHz when 10.3 dB. Passive mixer different, AD831 insertion loss not exist without an external duplexer does not need to be a passive termination.
