1. 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 imaging and other applications 2. AD831 provides +24 dBm third-order intercept , which can achieve -10 dBm LO consumption. It does not require high- LO drivers, and there is no corresponding shielding and isolation problems. Therefore, compared with passive mixers, it can System performance, reduce system cost. . 3. The mixer is designed to be powered by a single supply, and the RF, IF and LO ports have DC isolation capacitors for easy . 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 pins OUT and FB 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 output amplifier of the mixer and the best source impedance, the SSB noise figure of the mixer is 10.3 dB at 70 MHz. Unlike passive mixers, AD831 has no insertion loss, no external duplexer, and no passive termination.AD8362 has two working modes: measurement and controller. In Figure 1, in the measurement mode, VOUT and VSET Product parameters: RF input: 0.1-500MHz RF input: +10dBm (1dB compression ) Local oscillator input: 0.1-500MHz Local oscillator input: -10dBm IF output: 0.1-200MHz supply voltage: 9-11V single-ended supply Weight: 11 grams Colour:Green Material:PCB Size:33x33mm Package Contents: 1* RF Mixer Module Only the above package content, other products are not included.
