1. The AD831 is a low-distortion, wide dynamic range, single-chip mixer, suitable for RF-IF conversion in HF and VHF receivers, second mixer in DMR stations, DC baseband conversion, and quadrature modulation and demodulation and frequency shift detection in ultrasound images and other applications.

2. The AD831 provides +24 dBm third-order intercept, which can achieve -10 dBm LO consumption. It does not require high LO drivers, and there are no corresponding shielding and isolation problems. Therefore, compared to passive mixers, it can improve system performance and reduce system costs.

3. The mixer is designed to be powered by a single power supply, and the RF, IF, and LO ports have DC isolation capacitors for ease of use. The operating frequency of the RF and LO inputs can be as high as 500MHz. The IF output is a single-ended voltage output. It has an output bandwidth of 250 MHz.

4. A single resistor connected between the OUT and FB pins is used to set the gain. The amplifier has low DC offset characteristics, so it can be used for DC coupling applications such as DC baseband frequency conversion and quadrature amplitude demodulation.

5. With the mixer's output amplifier and the best source impedance, the SSB noise figure of the mixer is 10.3 dB at 70 MHz. Unlike passive mixers, the AD831 has no insertion loss, no external duplexer, and no passive termination. The AD8362 has two operating modes: measurement and controller. In Figure 1, in measurement mode, VOUT and VSET.
