DESCRIPTION
AD831 High Frequency Transducer Mixer Module 500MHz Bandwidth Frequency7744
1. AD831 is a low distortion, wide dynamic range, single-chip mixer, suitable for -IF down conversion in HF and VHF receivers, second mixer in DMR base 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 point, which can achieve -10 dBm LO power consumption. It does not require high-power LO drivers, and there is no corresponding shielding and isolation problems. Therefore, compared with passive mixers, it can improve System performance, reduce system cost. .
3. The mixer is designed to be powered by a single power supply, and the , IF and LO ports have DC isolation capacitors for easy use. The operating frequency of the 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 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: power measurement and controller. In Figure 1, in the power measurement mode, VOUT and VSET
