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
