Feature

●High Intermodulation Extract Point: The AD831 audio mixer offers a third-order intermodulation extract point of +24 dBm, realization of -10 dBm LO power, without the need for a high power LO drive.
●No Shielding or Isolation Issues: The music mixer does not require additional shielding or isolation measures, improving system performance and reducing overall system costs.
●Single Power Supply Design: The mixer is designed as a single power supply, RF, IF and LO port with DC isolation capacitor, easy to use.
●Wide Frequency Range: The RF and LO inputs of the mini audio mixer can operate at frequencies as high as 500MHz, making it suitable for a wide range of applications.
●Single-Ended Voltage Output: The IF output of the small audio mixer is a single-ended voltage output, providing ease of use and compatibility with various systems.


Description

The AD831 is a low distortion, wide dynamic range, single chip mixer, suitable for HF and VHF Receiver RF-IF frequency, second mixer in DC-baseband conversion, quadrature modulation and demodulation. Features:With 250 MHz output bandwidth.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 in DC-baseband frequency conversion and quadrature amplitude demodulation.When the mixers output amplifier, the SSB noise figure of the mixer is 10.3dB at 70MHz.Different from the passive mixer, there is no insertion loss, no need external duplex device, and no need passive termination for AD831.Specifications:Model: AD831RF Input: 0.1-500MHzRF Input: +10dBm (1dB compression point)Local Oscillator Input: 0.1-500MHzLocal Oscillator Input: -10dBmIF Output: 0.1-200MHzPower Supply Voltage:±5V Dual power supplySize: Approx. 7*5.3cm/2.8*2.1inchWeight: Approx. 12g / 0.4oz Package List:1 x Active Mixer Module
